No way s0n gonna rig this shit again..
BLG, NRG, T1, TH is another group of life and hear me out. BLG whilst they have been strong in recent time have a bad tendency to falter against very organised teams - in addition, they have an interesting match up history with NRG. NRG whilst they are now in the Top 2 still use relatively old comps. DRX slipped into Champs despite a very rocky performance in the playoffs. TH are the most hot-and-cold team since they can dominate for a few games and drop off a cliff the next two. Going from 5-0 in Groups to 0-2 in Playoffs with an 0-4 map record feels like TH could easily lose matches they were meant to win. T1 have been pretty shaky and could also lose to their own mental as well.
You could also consider BLG, GX, T1, MIBR since MIBR is another team that slipped into Champs despite a terrible showing in Stage 2 and Toronto. GX are dark horses, but I feel like they can end up being stale if ara isn't having a monumental game or Westside isn't clutching.
Edit: Mixed up T1 (3rd) and DRX (4th)
