Probably not DFM. TenTen has played like 4 agents in his entire career, all of which are either duelists, chamber, or kayo. Meiy is already playing all these agents, so I doubt TenTen goes there. TenTen also said he's willing to play senti,~~ but I think Medusa is igl, so unless they have a plan for that, I doubt they kick Medusa. ~~I think Zeta is also not likely to sign him. They learned their lesson the first time when putting an unestablished player in an off-role (cough hironronn).
To be honest, I have no clue where he'd go. T1 needs a smokes player if anything, but I could see a world where they put izu back on smokes. (with xcurrate to sentinel). DRX and GENG are chilling with their rosters right now as well. Unfortunately, in my opinion (KEY WORD: opinion), I see him going to GE. GE did say they were planning to sign korean players (last I checked anyway) and they are also planning to nuke their roster, so if he's going to franchising, I wouldn't be shocked to see him go there...
Edit: I have been informed that Medusa isn't igling. In that case, there is a pretty decent probability that TenTen goes to DFM.
