the current matchmaking is honestly a joke, always has been in my opinion...but, that being said here are a few things that should be done in order to make the game better for everyone:
-have matches based off of ones RANK instead of THREAT LEVEL (due to the folks that dethreat when they hit max rank/high rank)
-lock* bronzes/greens to their own server, silvers to their own server, and golds to their own server (so threat becomes balanced)
*if they so choose, there should be a server that mixes everything into one (much like what we have now)
