Not crazy at all, everyone is entitled to their own opinion. I don't see it as overpowered compared to other things you get early game, more mana, walk speed, and etc. It's just a choice of equipment, do you want more mana, more damage mitigation, more health? It's just a choice you can make.

i agree it is good but it is better on some demis at start then others  on sedna it anit much help seeing as she can heal 

but i do use it for reg and tb because they are weak in that area

Early game, especially as UB, I prefer getting:

Banded Armor

• Cost: 550
• +400 Health
• +5 Health Per Second

UB Base Stats

Taking your word that 600 armor increases mitigation by 10-15% (auto-attacks only), scalemail is less efficient than the extra health.  At level 1 +400 health would be equivalent to (1550 + 400) / 1550 = 1.258 or +25.8%.  Even if armor mitigated damage from abilities along with auto-attacks the health would be far superior.

EDIT:

To make things easier I am going to say 600 armor will give you 15% mitigation and mitigation is taken into account on all damage (which is definitely not the case).

For the 400 health to be equivalent to the 600 armor the current health of the player would have to be:

1.15 = (x + 400) / x or 1.15x - x = 400 or x = 400 / .15

= 2667

And that is if mitigation worked on all damage.

This is a java applet that I made a few years back for a Relic game called Impossible Creatures.  Each point of defense in the game corresponded to a percent of damage reduction.  Damage was in damage per second.  It doesn't take health regen into account(you'd have to treat this as a reduction in damage in the alternative setup), but you could use it to compare your two set ups.  The big thing is that if you have high health regen, armor benefits you significantly more.

Don't pay attention to the power stat.  It's designed to be a good approximation for comparing multiple weak units to a single powerful unit, as an example, five 100 power units should be roughly equivalent to one 500 power unit.  This was needed in IC but is totally irrelevant for demigod.  You want to look at the lifespan stat.  If you want the proper power stat for single unit comparisons, it's actually ((damage per seconds) * health)/(1-defense/100).

On sedna, at level 1, extra health wins by about a second even without taking the extra regen into account.  With the damage adjusted to account for the health regens of each version, sedna with the Banded armor comes out ahead.

I dont remember where i saw it, but someone made a really good mathematical exploration of health against armor, and im not denying banded gives you better results after all it costs more, but really armor + regen + heal, its the best combo, sedna got the regen and a great one and has the healing so what im saying is that for sedna is better armor and regen than hp.

I prefer Banded Armor over Scale Mail every time, but Scale Mail can be a good supplement when you want a little extra defense, and are either saving or just spent your gold. It's also useful against Erebus and Queen to prevent negative armor conditions.

uh, actually early game a sedna meless a lot, with sednas heals, i can melee almost any class without problem and as i melee they tenf to melee too.

Agreed, but ub normally spits and atack unless he im near a tower, UB and Reg dont normally get near me, but sniping people from close range and with full life is stupidity unless someone else is fighting me, Rook tends to feel safe in his forest so he fights, erebus melee bites , melee a little more and run, erebus and rook can kill me early game if im not carefull but either way early game people do more auto atack than skills, except of course torch bearer and other casters.

armor is majorly helpdful againist dps's like reg's and ub    i had over 3000 armor on my tb
