What? Have you really been watching Asuna? he plays all 4 duelists (not including Yoru of course) for 100T and he's been doing that really well for a minute now. His jett's fine. They need it on Haven for the anti-rush and picks cuz there are 3 sites to defend.
What 100T needs is for the rest of the team to step up because Haven is hard to carry individually. It's too bad Ethan had a bad time.
