You're suggesting that it remove debuffs on the demigod.  That is essentially temporary immunity to status effects.  Sure you'll get hit with the next cast, but none of the immunity granting abilities will save you from that.  It's on a fast enough recharge that you can use it once a fight so it's comparable to other immunity items in terms of recharge.  The difference is it's a 250 gold consumable.  Regardless, this is just arguing semantics.  The point is you could always save it to make retreating from UB far easier than it should be.  You wouldn't have to worry about overextension until you're at the same level of health as vs any of the other DGs and that would take a huge bite out of UB's early game usefulness.  Also, the cooldown on spit may be trivial at the start of the game, but later on when fights easily last just 3-4 seconds before someone dies or retreats, you would be able to use them to completely negate the skill points your enemies have invested in status effects.  I'm guessing it's like this already with the symbol of purity but at least you can turn favor items off(and as mentioned, you're choosing it at the expense of a favor item that augments your specific build).  I don't think we really need a consumable that does this to be honest.

There are people who think otherwise Doggie, we'll just have to see how it fairs when it is applied to future patches.

Some of those people also don't realize that there's a favor item and all four generals can counter it.

There is a favor item, and it works nicely. Adding the item would certainly change a lot of things, but exactly for the worse. Unclean would still be quite strong against fellow assains, and depending on how the scroll can be adjusted to make its use not fully replace the favor item has not yet been determined.

So we can't have UB strong vs 3 other demigods yet 3/4 generals can also give their team-mates their counters to spit? Some abilties are going to be stronger vs certain oppenents that doesn't need to be changed. In fact it would still be balanced if they removed symbol of purity.

Heaven forbid you change your strategies based on the actual outplay of the game.

There are better favor items to take than the 20% cooldown one for UB, especially in smaller games. It takes 10 seconds for Spit to do all of its damage, a few seconds longer than its cooldown.

I usually save staff of renewal for playing TB or even Reg some times.

Actually your spit stacks with itself. However it only takes one symbol of purity use to purge them all.

   Okay look, the point here is simple. The very fact that you need a favor item in the first place, Symbol of Purity, for Assassins most of the time is why this is an issue. Yes, we know it works, and I agree it does, but the rock bottom point is that you have to use a favor item to counter it. Players need to be on equal playing ground, each player should be able to choose a Favor item which is complimentary to greater objective, not simply one Demigod. Brandishing a Symbol in a larger Demigod game will often lead to a loss becauee the enemy gets to use the ones which gives them advantage, while you are forced to use poor items just to survive one Demigod's attack.

   Aruge all you want about "Oh that's just how it is", well let me tell you, that's not exactly how this game is intended to play. This thread has been created to see how people thought about it, but no one is really providing any sound arguments on why a scroll to shed away negative effects is not a good idea. Heck, in hindsight it probably could even use an alternative use. Such as being used on an enemy Demigod to remove positive effects. Such as Bramble Shield, Oak's Shield, Last Stand, and various other things.

   Just last night did a 4v4. I played a Queen, and someone else played as Queen. We also had Sedna and the ridiculously powerful Unclean Beast. The two Queens had the exact same Bramble build, and we just kept spamming shield over and over and over and over. Out primary melee Demigods never took damage, it was an easy win because even in mass the enemy just couldn't ever deal damage. It's be very nice to have something to make shields and other positive effects useless for a short duration, and that'd probably even include heal too.

The arguments are there.  You're just ignoring them.  Status effects cost critical skill points to invest in and they can change the outcome of a fight.  If you can purchase a 250 gold scroll and just shrug them off, their value will be questionable early on and they won't scale well at all once the fights are over before their status effect incurring spell recharges.

Saying that favor items should be used only to augment your own build is simply short sighted.  You use the tools you are given to whatever their best effect is, that is the point of the game.  If you get more mileage out of a favor item that directly counters your opponent's build, it makes perfect sense to use it over one that augments your own.  It will often set them back further than it sets you back.  Also, I think you are underestimating the symbol of purity.  Being able to counter an important ability of your opponent's is huge.  A few years back, I played a game called Impossible Creatures.  In this game you got to create and choose the units in your army.  Now, everyone used walkulas at level 2 because they had reasonable damage, camouflage(they were invisible when not attacking), and health regen(which is not on everything in the game).  The walkulas had a significant advantage over other units because they always got first hit and always got into melee.  The reason for this is no one had keen sense(a passive ability that detects all invisible things in a radius) units.  Along comes the coyagon.  The coyagon had identical damage, less health, and more armor.  Since it also had health regen, it benefitted a little bit more from it.  The coyagon also had keen sense, so the walkulas were always visible to it.  It could beat walkulas in melee by a reasonable margin because the walkulas weren't getting first hit all the time.  It also spotted the walkulas for any ranged units you built along with the coyagons.  As such, most people started using coyagons and stopped using walkulas.  Now there are other combinations with abilities that enhance their own attributes rather than countering the opponent's, but these were not widely used because in the case of walkulas, it was more important to be able to deal with the camouflage than to dish out extra damage for yourself.  Now, demigod is not Impossible Creatures, but the principle behind this example still holds.  More often than not, countering your opponent is more important than making yourself more powerful.

Generally when you want something nerfed (which is what you're asking for) you need to prove it should be. Spit has multiple counters one of which is don't let UB get that close but you act like generals and symbol of purity is the only way. Symbol of purity is simply one way of countering it. Another would be to itemize more for health then damage or to carry potions to counter. If I face a UB with an assassin which isn't that often which is weird if UB's "so powerful." I take into consideration that i'm facing a UB, spit is his only strength so I need to avoid dieing early so I can starve his cash and stop his early game advantage. No pont in typing them up though, as you'd dismiss them anyways.

Having to take into account UB's spit is no different from having to take into account sedna's heal or QoT's shield. It's the main focus point of the demi-god and unless your scroll counters all the demi-gods focus points it's being biased to hating one demi-god. So yeah i'll be all for the scroll if it:

Stops sedna's heal, Qot's shield, Rook's hammer slam or towers, regs snipe or mines, erebus' bite, TB's deep freeze and fireball, and oak's shield. Plus removing spit, as then it's balanced, but to do all that it'd need to cost as the bare minimum 1500.

No one's forcing you to take symbol of purity, it's simply the easiest none general spell to counter it. That doesn't mean there aren't other ways.
