Its just slidshow baiting. G2 bo5s are always dodgy. The fact that even sen made it close in na was always the sign of loopholes in g2. And losing after 2 maps ban summed all up.
Making stupid predictions is fine, but saying that a team didn't deserve to win after they legit beat all the best teams in the tournament is absolutely braindead.
Saying G2 is overall a better team than T1 is not saying T1 isn't good or didn't deserve to win. It just means G2 wasn't at their best and are more likely to perform later in the year too, which frankly, I agree with, and I'm a huge America's hater who was routing for T1 the whole event.
