I think IMT is overthinking things. I think they spend so much time creating perfects comps and strategies, that they lose their adaptability. If they get something wrong, they can't change quickly, and try to force it. I mean, WildTurtle still tried to out duel people as an ADC despite being behind in gold. His aggression works well when he is ahead, but when behind he collapses.
They might fix that, they might not. But they don't appear to recognize their flaws, while Regi has admitted to everything he did wrong last split, and is trying to fix it. TSM is evolving, and I don't think IMT will be able to keep up.
