Roster Change Predictions:
North has dropped Cajunb (no surprise, was very stale and didn't bring the X-factor with the AWP)
BIG should be dropping Legija but we'll see if they can grow a brain
Envyus - Dropping Sixer and Happy - Probably picking up Zywoo or to1nou and another fragger. This is if rpk can make a full recovery soon
Mouz - Dropping ChrisJ, potentially Styko - Adding of some FPL god(s)
VP - Dropping Taz, adding Michu most likely
Optic - Dropping Allu, picking up Dennis, although Dennis and the NiP account have been reacting to each others tweets for a long time but I don't know if it's enough to say he's going there
Flipside - Minus Markeloff and Blade (or whole team could be dropped by org) - Adding of CIS talent, potentially Vega members but they renewed their contracts a few months ago
Anyhow, these are my predictions and just speculation. I'm excited to see what 2018 has for CS
Edit: Faze will buyout the entire C9 squad since they won the major and Faze doesn't deal with losers
