thick hide:
Increasing your armor value from items by 3-7-10%.
Additionally increases your chance to be missed by all attacks made against you by 0.1% per 300/200/100 Attackpower or part thereof while in bear form.
btw: is this "per xy or part thereof" correct english? I searched for the right expression on a dictionary, because english isn't my native
it should mean if you have 4500 attack power you gain 4,5% to-be-missed, if you got 4501 AP, you gain 4,6% to-be-missed.
dunno how good it would scale... maybe an 1:2 or 1:3 conversion from expertise and hit? 6% expertise and 3% hit would be 3% to-be-missed?
something like this would be a good version...
