I feel like Olof would consider joining Fnatic again, but your point about S1mple stands/ I don't think that S1mple to FaZe is likely, but I'd like to see it happen.
I thought the same with Flusha too - I could maybe see JW stepping down to focus on streaming, but again quite unlikely.
C9 Karrigan is a real possibility, and Wardell turned down the chance to play with a struggling NA team, not a strong EU team - I think that there's a chance, and even if he doesn't join its just a move that I'd like to see, not one that I think will happen
Vitality right now are doing well, and they shouldn't make a change for at least a few months, but AmaNEk is better than RPK so he'd likely make them better
