I feel like the current roster should work with another year, but at the same time they could do with a seasoned IGL.
Option 1 - keep Marved on IGL, full roster stays, maybe make TenZ a sub and sign Nismo, put Zekken on full duelist.
TenZ is undoubtedly not bad at all and wasn't the problem, but also not the full solution, and could definitely make for a really good sub, which would also allow him more time for personal stuff, especially with Kyedae's current situation. also means he can stream more which is never a bad thing for TenZ fans.
Option 2- Bye Bye Brazil
TenZ
Zekken
Marved
Johnqt*
Zander/eeiu
Although I personally think this is worse than having the Brazilians, given their experience and ever-improving English, with this comms will improve in terms of faster conveying of info. the M80 are by no means weaker than the average T1 team, and with the new IGL in Johnqt can bring fresh ideas to the team. the roster will likely be rounded out by another Canadian, either eeiu or Zander, depending on how the team feel out the roles to be.
Option 3 - No changes at all.
Just tank it out with the current roster, and hope it goes ok. It could work, but so far not worked yet.
