Unless il80 changed something, accuracy still counts but it's not too important. When I was leveling my pvp rank in wolves den I started in pve pld gear and never missed even when blinded. As I dropped my acc gear for dps stats though I started to notice misses while blinded.

So it's not a completely worthless stat, but it's pretty far down there. Wouldn't kill you if you had it on you if you had to choose between parry and acc.
