BF3 I played I bunch, plenty of 3rd party servers are local, so little ping issues(still get the "went around the corner and died " ones, but that's client side hit detection working, so, yeah, business as usual). D3 is just shit all around, every time, all the time. WoW I used to raid hardcore 10 man, little issues, save those on tight ping requirements (hello heroic rag sulfuras smash, I'm talking about you). So no. D3 is a different beast. It requires a flawless connection, all the time, every time. And that makes it unplayable to me.
