Suck it up and deal with it. Not every 4 stack is an elite tier team. Does it help sure, but it doesn't mean you are going to lose. Faced tons of 4 stacks and taken down alot of them when solo matchmaking. People just need to suck it up or try and find people to play with in a team, instead of just quitting because they see a 4 stack or whatever in any gamemode.
