There are a lot of interesting story lines
A lot of new rosters will be debuting at a big event, probably most notably Astralis and VP. C9 will have to prove that they have the consistency to be a top level team, and SK has to prove that they aren't in a slump as they tend to be after player breaks
NaVi had better not blow cock or they'll be a laughing stock after having lost to epsilon as well
Personally I'll be roosting for both mousesports and faze (hopefully no choke...)
