The big issue with Garbad is he wasn't able to separate his excellent skill and knowledge of the game from his desire to troll the shit out of people and pick fights.
As a knowledge bank for this game he is one of the best. Able to convey to others what he is doing and how they can emulate his performance. That's something not many high skill players are capable of. Sharing knowledge isn't an easy thing to do.
He just needs to stop trying to poke the anime kids, arty players, etc.
