Would've been nice if you had posted the matchups (with records), and then your predictions after that. Either way, I disagree entirely with a bunch of your things.
-NA, Round 1-
CLG vs TL, TL wins 3-2- I see this series being closer than most people expect. While team liquid didn't exactly "light it up" during the latter half of the split, let's not forget that CLG was a hot mess for a decent chunk of the season with many people (including myself) thinking that Huhi was one of those challenger-level mid laners pretending to be an LCS-level one (someone comparable to the likes of Alex Ich or Keane). While I don't see either of these teams advancing out of the semis, I trust the combination of Dardoch/Fenix/Fabby more than I do the combo of Xmithie/Huhi/Stix
C9 vs NV, C9 wins 3-0- Not exactly much to say here, C9 is a middle of the pack team whilst NV realistically shouldn't even be in playoff contention due to their final game being against the soon to be relegated echo fox. C9 should very easily win this series, but much like the other I am highly skeptical they'll make it out of the semis.
-EU, Round 1-
UOL vs GIA, GIA wins 3-0- Not exactly a hard pick here, with UOL being outclassed in pretty much every position barring support (bit of a hylli fan). I entirely expect this series to be mid-lane focused, as Exileh and Night have been two of the most talked about players at this position all season. While Night has enjoyed a pretty decent rookie split (posting stats similar to the likes of Ryu and Fox), Exileh's has been rather "grey" so to speak. If UOL wants to win, then they'll have to camp mid-lane and try to push their weak link ahead. That being said, Exileh has the 5th most deaths in the league (with the 4 other players with more being in the promo tournament), so even with that happening it may not be enough
H2K vs FNC, FNC wins 3-1- Arguably the only reason to even watch LCS over the next two weeks aside from the promo tournament (which I'd advise everyone to watch, if only because Misfits/C9C have realistic shots of winning an LCS spot this split), both teams are coming in with "makeovers" so to speak. After having wrist issues for most of 2016, Freeze is finally forced to step down in favor of the Greek Menace (to his own teammates) forgiven, while FNC weirdly decided to sub in Werlyb after acquiring Kikis halfway through the split. While I am highly doubtful either of these teams will make it past splyce, history and meta are heavily favoring fnatic to win, something I have to agree with.
You'll get my round 2 predictions once those begin...
