mustardoverlordikinclark561a team of 6 players, that are all the same person, would have perfect comms and perfect synchronization, so i feel like almost any invite player (that isn't a med main) would win.
My hot take is that this isn't nearly as true as people think, bc a lot of players are a lot more comfortable playing one role- more vs less heals/aggression/comms etc
I think the obvious first candidates in the hypothetical would be Invite multi-classers like botmode who are comfortable on either combo or flank. A factor I didn't think about is whether they're playing a stacked froyo roster though
