Well, considering Perfecto does a lot of entries successfully on the T side, I'd say Flamie simply fell off. Most of his mistakes are on the CT side, so there's no excuse.
I'd like to see him on the team as a 6th player, but I think that if they change the coach, even Flamie could improve. They have 0 impactful strats right now. They look lost, especially the other team reads them.
