I'm a brazillian, as are all my Bnet friends, of wich I have more than 30 online at any given time since D3 released. The major problem for me and everyone I played with since launch is one: Lag. It varies from unplayable to tolerable but annoying (My wizard casting disintegrate, then switching to the energy neutral skill and there's the lag. Stopping casting to move and there's the lag). As I said before, it's every single one of my friends I've played with. And that's why I'll be playing T2 the day it comes out, and that's why I'm trying my best to sell the game to every one of my friends on Bnet, so we don't have to deal the unnecessary, uncalled for lag that the always on drm causes.
