The roster's being built by Bjergsen, but there's no denying that Doublelift > Turtle in terms of mechanics and consistency. There's been two splits in a row where Turtle has underperformed or straight up been careless in games, and just getting rid of him is the right change. Maybe he can find success somewhere else, with a team better suited to handle him going balls deep for no reason.
There's a lot of rumor that we're likely to see TSM Adrian as well, which I'm excited about- two import spots left for top and jungle, and Adrian was so underrated on TIP. IF TSM picks him up, I think they could easily make it work.
My dream roster would have to be Zionspartan/Rush/Bjerg/Doublelift/Piccaboo, though it might be hard to manage. Very, very strong solo lanes with the potential to grow into absolute monsters with a strong coaching staff, the arguable best jungler in North America, and a STRONG bot lane duo. As a bonus, Piccaboo speaks relatively fluent english, well enough to communicate. He's also an extremely good shotcaller, and Piccaboo/Rush on the same team... the same as Score/Piccaboo but even better. that would be a world class team, with proper coaching staff.
