He likes NA because he feels they have better organizations. According to a conversation/interview he had with Thorin he is pessimistic of his chances that someone will take a chance on him and pick him up.
He is a good player and works hard, he is also a very emotional player and that has led to consequences. He wants to be the best, and when it comes down to it, that mentality is what you need in a player and a teammate. A good organization with good coaches might be able to reign him in. With that said I don't feel TSM has the coaching and support staff in place that would be compatible, they also have WildTurtle and Keith, they need to fill other roles, and would likely keep their ADC slot NA.
It might sound crazy but I think Renegades seems like the best fit. Their ADC situation is shaky, and I think Monte would pick him up.
In any case, I hope he stays in the pro-scene.
