If PVP matchmaking is RNG, why are premade Parties still allowed in Fronlines?

"shut up", "stop taking this seriously", or "idc about winning", and when they dont listen you get "bad callouts LMAO Lol"

These are definitely the worst people to get on your team. The people who never try, and never care, or worse, either AFK or run straight into enemies and feed them.
I'd take getting spawn farmed to oblivion and end the game with 0 points over carrying 5 AFKers to victory tbh.
