H2K certainly fixed their issues. G2 definitely didn't.

H2k were already competitve, and their biggest issues were mid-game/late-game macro, whereas g2 had a week overall showing, with almost nothing redeeming. Also, I think FW will imrpove over c9 since FW's mistakes were more obvious and macro based, which should be easier to fix.

Anyways, I think it's fairly likely FW win the rematch based on how the first game went, and I don't see FW losing to roadless Imay. FW vs SKT could be FW's first Korean loss, but I also think it's more likely Karsa wins FW a game against SKT again than meteos, as SKT's weak point is bengi/blank. This sets FW up for a 2-1 or 3-0 week, which puts them at worst at 3-3, and C9 losing to FW and SKT puts them at 3-3 too, where a tiebreaker occurs. Of course if C9 do beat FW, it's very hard for FW to make it out, but I'd bet against that.

Sneaky vs NL and Impact vs MMD

Sneaky vs NL is a missmatch, but FW have managed to win against worse missmatches (bang, pray vs NL), and sneaky isn't a massive lane bully, so SwordArt can save NL pretty well. Impact hasn't shown up as much as expected, and I don't think he'll crush MMD enough for the mismatch to be noteworthy, whereas Karsa is much better as pressuring lanes than meteos, who seems to hyperfarm. Either way, it almost all comes down to the 2nd FW vs C9 game, which I think FW should win.
