Rook is big and heavy. That kind of bulk always comes with a speed penalty. Small and fast, big and slow - one offsets the other.

He has the most HP in the game and one of the highest armour.

maybe its shoudl be 5.6 speed instead?

that way if a player chooses to yse swift as favor he can be 0.1 faster than UB or erebus' base speed giving him a minor speed advantage.

Sedna's high priest type took few month to fix. How long would this take

Rook has some of the lowest armor.......

I'm not sure what's huge about his stats. He has a low attack speed, low armor, and good HP. He is huge, making him the obvious target in battles. Hammer Slam and his shoulder upgrades are great abilities, but they are all counterable. I agree, Rook has great abilities, but he's not overpowered, and he doesn't need a 10% speed reduction.

he gets very much hp and after some levels. it would make him nearly immortal with normal speed. ub is indeed faster with the second most hp, but he cannot hide behind tower-farms and cannot dmg while fleeing.

ever played against a speed stacking rook? you never saw your base being rippied apart so fast. but you could counter this by buying early boots and stuff like that to be faster again.

Wrong! he's got the lowest armor in game! at least it is in 1.00 version!

compare this:

Rook      HP: (1.lvl)  1900   >   4750 (lvl 20)  Armor:  240  >  658 (the lowest armor in game!!)

Oak       HP:    ...     1700   >   4360   ...       Armor:  400  >  875 (pretty low for oak actually, if you compare it with 

 reg, sedna, torch .. everybody!, considering that oak is just 'a soul in armor' as story says)

Erebus    HP:            1650   >   4405             Armor:  220  >   885 !

Beast      HP:            1550   >  4115             Armor:  475 ! >  1083 !!!

... and actually all demigods stats (including mana&health) should be considered to change, it doesnt looks to me too good now.

and i agree with 5.6 for rook! (i would also considered some movement buffs for some other chars(demigods), like +move speed for reg in angelic fury, + base mov sp for thorch in fire mode (look, ereb has got 6.3 always and he is like 'flying' (levitating), but also is Thorch in fire mod!), then + mov sp for QotT if compost is active!(with also other buffs which compost should give her, like extra att damage), then i would actually give sedna 6.3 base speed but reduce hers speed buff from inner grace (but in addition give her some other extra effect for that - i got some pretty radical ideas actually), and finally beast, yes, if inner beast would always give max +10% mov, then i would give it 6.4 base!

rook:

exactly, because he is big he should count as having bigger steps, so therefore his mov sp shouldnt be that small, 5.6 is my vote! (although even 5.5 would be good of course) And i do agree: speed stacking rook sucks, and this could change it a bit but i have also seen fast rook (journeyman's & wand of sp) it looks terrifying! but still it is beatable (easier than some other demigods)

Well, it's nice that a lot of you want to see his speed bumped to 5.6. I vote 5.8.

Also, I don't really care what would happen in real life. This is a videogame.

I'm not really sure why rook's so slow. If they were going to adjust his speed, which they probably won't, I think 5.7 would make the most sense.

I agree in theory that this was the intent of Stardock, but I do not agree with it in practice. Regulus, Sedna, UB, TB, and Oak can all give Rook a fair fight. He's not so powerful that he deserves to have his movement speed reduced by 10%.

Exactly my feeling.  Sounds like an overnerf from beta.
