Honestly, I thought this was a joke thread judging by the title.

I like complexity in games, and currently, accuracy is the only stat that is wasted above a certain threshold. Even if it's frustrating to see a "wasted" stat on your gear, it's only wasted on that piece of gear because of the other gear you have at the time. The have set up the gearsets so that you can be over accuracy caps so you don't need a specific set to meet the accuracy cap, and so you can meet those accuracy caps before having cleared content.

I'd like to see more non-linear stats, but... that isn't likely to happen in this game.
