As someone who has paid attention to almost all of the "news" surrounding the offseason, I can definitely say that this has been thoroughly entertaining. I'll just list off the stuff based on region:
NA
-IMT tells players they can field offers from other teams, Adrian signs immediately with P1 (with allegations that Echofux tried to poach him afterwards, more on that later) and Reignover signs with TL to fill the spot left by dardoch (again, more on this later)
-Dignitas/Apex bought by Philadelphia 76'ers/rebranding back under the original dignitas banner, many people suspect that they're potentially going to field a super-team with names such as Huni/Gorilla being potential imports
-Echofox nabs dardoch off TL, but outside of the rito-approved window (meaning that they're probably not going to be allowed to use him in 2017)
-Rito "apparently" gives Echofox a lenient/non-existent punishment for trying to poach adrian/potential other players, teams are suggesting that they're going to refuse to scrim with them during 2017 as their own form of punishment
EU
-Fnatic 2017 roster revealed, featuring Soaz/Amazing/Caps/Rekkles/Jesiz
-Paris St Germain (team who bought huma's eucs spot) reveal signings of blanc and Pilot, two former members of JAG
-H2k potentially signing Febiven to replace Ryu
-Former Roccat support Raise leaves team, joins JAG
LCK
-Longzhu/CJEntus/Afreeca Freecs/KT release their rosters, with notable UFA's including Emporer (the TDK adc we all love), Madlife (:O), Lust (aka lustboy, former TSM support), and Mickey (the guy who made CJE games watchable)
-Rox allow their players to explore other options (similar to what IMT did, because we're not allowed to have multiple good teams), Smeb joins KT and Peanut joins SKT
-KT Rolster also resigns score and adds smeb/pawn
Not including LPL because I find that region rather boring, think I got "most" of the important stuff though.
