I don't know what that Titan fight video is supposed to prove. Whenever you got hit by weight you were clearly late to the dodge, but overall, you were dodging fine weren't you. The problem with blaming lag for dying is that people think it makes some kinda difference. It does not matter if you die in the fight because of lag, or because of unskillful play. When you're dead, you're dead all the same and not pulling your weight.

It does not mean someone is an idiot or a retard, however, it's just means they aren't useful in the fight. At least you can improve your skill but if you blame lag... there's usually little you can do to improve that in any reasonable time frame if router/client reset doesn't solve it.
