More clarity on what this mode is supposed to be would certainly be helpful. That said, I'm not sure the only solution is to go full beans in one direction or the other. Dropping a target number on an enemy, for example, is not IMO over-coordination, simply sensible PvP play.

I very much agree that the current system and skills that favor LB coordination and thus light parties with certain compositions creates lop-sided, thus dull, matches. But I favour 3-tier matchmaking or queue separation over eliminating all forms of coordination.
