Is AC broken?

[TheFishyOne]

I heard from a warrior guildie that AC was broken in some way, and that he was focusing on stacking HP. Is this a warrior only problem, is everyone affected, or does it simply not exist? If AC is broken, exactly how? I'm an Iksar Monk, so this is a direct concern of mine.

AC seems to be working fine, level has more to do with it than anything (as its always been). For warriors, priority is usually AC/HP/Dex. Monks, i would say priority AC/HP/STR
