I've got the same problem. Its really annoying.
Yes, i've checked the talents (elemental precision 3% +hit) and the Draenei racial (1% +hit)
I, wether in raid or in rawr, count on +hit debuffs wich are applied by others, so I left Misery/ImpFairieFire for calc.
I am hitcapped trough my gear (346 +hit (=+4 above cap))
