At the same time, my offspec Ret set gets over hit cap very easily - I even bought the EoV bracers (I think - those or a BoE naxx-25 drop) because they had no hit on them and the hit on my old ones was completely wasted since I was overcapped.
Even for raiding, hit up to the PvE melee hitcap is plentiful. Don't pick gear because it has some hit, you'll always be able to get hitcapped.
