I technically have, I guess. I have 3 32's. I have a grimoir score of almost 2700, at 2660. The max grindable right now on my platform (Xbox 360) is like 2860. So I'm almost done until DLC comes out. I've got every raid piece so far, and guns to boot. I also own one of nearly every exotic in the game.
So I guess I'm as close as "beaten" it as possible. All I do is PVP.
