If any stat should be removed/replaced, it is Determination. It is triply redundant as Weapon Damage and Main Stat already do what Determination does.

That aside... Accuracy is a good thing. It makes building a set of gear somewhat less boring. Instead of just having to ask "does this have the stat(s) I like?" when you get a new piece of gear, you also have to ask if you can still hit things if you equip this piece. It prevents things from being a mindless climb to the top where the only thing that matters is item level. In a world where there are constant complaints about how bland gear is, removing Accuracy of all things will just make it worse. I do, however, support the idea of Accuracy over a cap translating into increased Critical Hit Chance. After all, if you're just that accurate, you're more likely to hit a weak spot
