-acknowledge co-op's existence
-fix lag & connection issues.
To be honest I don't care what they do with gameplay at this point, it seems anything they do to one gun or mechanic will have consequences in some other aspect and induce rage into a portion of the playerbase, so I would just like to enjoy the game without being disconnected constantly and having 8/10 games suck due to lag.

Co-op, co-op and more co-op the competitive players had there turn now its are turn.
If co-op players got the support competitive players got there would be more gamemodes more fixes all this means there would be more co-op players.
Sadly this will never happen.
