this is so abusable, mw3 could be way better on here but tryhard kids are always stacking one side- not to mention these ppl will freely switch to your team/spectate you and tell their friends your position on discord
suggestions are: autoassign only
parties set up the same way as old mw3 (through steam invites)
limit of 3 ppl max on parties
no spectating 
keep avoiding the grind
