It can be frustrating in a multiplayer game when you feel like your teammates aren't preforming up to your standard. However, I don't think there's much that can be done.
I'd wager that the average player of any game is not that good at it. Only certain players care about improvement in and of itself, others are happy if they're winning and will cheerfully do what they want until they hit a wall. At which point they will either improve themselves or move on to another game.

SE could impose a challenge that must be passed before queuing. My understanding is that WoW had something like that called Proving Grounds but eventually dropped it as a requirement to queue.
Most likely the people who approve of such gating can pass it without issue while those that actually need to improve will only be motivated to complain about it or move elsewhere.
