This has already been discussed and addressed in this thread if you actually took the time to read it.
You can find further information here:
A) Developers, a CALL TO ACTION. Mutliplayer needs FIXING! - for why custom ranks is important
and
B) Devs, please separate Multiplayer Ranks! The 1v1 crowd want QS, 2v2/3v3 want custom! - To see why we want seperate ranks.
Stop trying to rehash the same silly points we’ve already addressed several times. This thread has reached it’s logical conclusion; there’s no point going over old points. Everyone has had their say, the devs must decide.
