Well, I was mostly right so far (not that it wasn't pretty obvious) and Biofrost joined CLG since aphro is officially leaving. There was really only two potential outcomes there, Aphro stays and Bio goes to 100T, or Aphro leaves (I'm guessing either to 100T or he's gonna retire/take a break to just stream) and Bio replaced. Also, reignover joined CLG. Reignover is a 'better' xmithie style jungler if he's playing well. However, overall that doesn't look very strong on paper, but CLG seems to get more out of it's players then many other teams. They do lots of interesting training that I think other teams don't. Hand-eye coordination exercises and such. Biggest question mark is who can fill Aphro's shotcalling shoes.
Svenskeren went to C9, which seems like a decent fit for him to go back to his aggressive carry style. Or, he might burn out completely like most ex-TSM junglers. We'll see.
Barring some import or rookie I'm not aware of, I think the bot lane for 100 Thieves is gonna be Codysun/Aphromoo. It's the only adc/support slots not determined yet for an LCS team, and they need two domestic players. They already used both import slots on Ssumday/Ryu. Everywhere else has someone solid in at least one spot. Like, Aphro would be an upgrade over lemonnation for golden guardians, for example. But, I'm not sure they'll sign a 2nd player and keep both contracts. Unless they move him to their substitute squad and he works more as a coach/analyst.
In EU news (not that anyone cares, amirite?), Splyce signing Odoamne, Xerxe, Nisqy and Kasing to go with Kobbe who stayed. Considering how the top teams lost a lot of talent (G2 and H2k both currently in shambles) that roster looks pretty solid in comparison. Fnatic is odds on favorite to be the best team currently, having kept 4 players and replacing jesiz with hylissang, which is a big upgrade on paper, while everyone else seems to have gotten worse. No one else looks particularly close right now, but can never be sure how everyone will work together and adapt to DRASTICALLY different meta with new runes.
Heck, Schalke04 looks pretty good right now, with a roster consisting of Vizicasci, Pridestalker, Nukeduck, Upset and Vander. I know nothing about Upset, but he doesn't need to be the carry with Vizi/Nuke/Pridestalker, and Vander is a very smart support/shotcaller.
H2k fans are in for a rough split I'm guessing. Pr0lly leaving was potentially the biggest blow, but then their 3 best players (odo, jankos and Febiven) leaving on top of that was a death blow. I'd be very impressed if they put together something good in the wake of that. G2 as well, Hjarnan/Wadid is no Zven/Mithy, and while Trick has fallen off, he still had experience with Perkz.
edit: Forgot Wunder signed with them, so their top is an upgrade at least. Expect was never anything special, but he played his role well. If they re-tool their strategy to focus on Perkz and Wunder, that might work. If this is where Jankos ends up, that could be something. It'd only be a slight overall downgrade from their previous roster. Bot is worse, mid is same, top is an upgrade and jungle is roughly same but different style.
