I really agree with a lot of what is said about the new C9 roster. C9 clearly wanted a roster built around early game, and Blaber and Vulcan are great prices for that. Blaber is very aggressive and Vulcan has a good champion pool for skirmish heavy teams (Leona, pyke, naut).
I am worried about what games look like when they don't get ahead early. Or even if they do get ahead early, who is gonna shotcall the mid and late game? As far as I know Sven, Zeyzal, and Sneaky were pretty big voices for mid and late game decision making, so now that they lost all 3 of them, I think they will struggle in that department.
