Iksar AC bonus consensus?

[beel]

Hi,

I am considering to reroll my 39 iksar monk as human. Reason? Fashionquest + exp penalty of iksar is boring (also, I regret my spending of the 20 starting skill points).

Only thing holding me back at the moment is the alleged Iksar AC bonus. Have anyone parsed this properly or can give some insight into how big (if any) the effect of this bonus is?

In before comments about regen and min/maxing: Yes, I know.

Thanks for any input given!
