Game Mechanics: Player Armor Class (Long)

[Martenus]

This is a feel Post i have no real Hard evidence to proof it but it seems AC has not the high impact it should be i have 1017 ac with my iksar monk on 55 and parsed like 30 mobs after that i took off my Ac gear for Ressit/Hp one just for another 30 mobs and there was nearly no diffrence with nearly 250 ac less got even less damge in resssit gear over those 30 mobs.
