Group A: probably the most definitive group to play out, fnc and drx qual easy, kru and blg can put up a decent fight and MAYBE an upset but I doubt it. fnc and drx have shown pretty heavy dominance, whilst kru and blg have looked okay but have shown alot more weakness than strength.
Group B: HOLY SHIT GROUP OF DEATH, both masters winners this year, masters shanghai runner ups and a team that has GREAT potential for an upset in FPX. This group will be nail biting until the very end. I genuinely think any team can make it out or lose in this group, yes that includes FPX (maybe a bit lower hopes of making it out but i think there is a chance)
Group C: This group on paper should be definitive. But in reality I think talon still is very big question mark in the strategy because of the introduction of primmie and their willingness to play unusual comps, Vitality has ALOT to show after basically being mostly middle of the pack for most of the year and Trace is a very underrated Chinese team. I think the only guarantee would probably be LEV but if there is any group for there to be a massive upset, it is this group.
Group D: This is the group to watch in my opinion. I think this is another group where you can expect some major upsets. All of these teams have shown dominance in some shape or form this year, some earlier, some more recent. EDG is still looking to redeem themselves after their performance in Shanghai, FUT have shown some very good highs but also some lows, G2 has very high hopes of making a deep run and PRX is a team that although is definately not as strong going into champs as it was last year, is still a team that you can never count out.
