Every game I'm forced to check player's stats for EM%, but sometimes I forget because I'll do something else or be talking some strategies with friends that I'm playing with. Then a 80% EM will sneak in and be on my team making it a 4vs5.
I don't care what you say about how he should still know what he's doing, but when he doesn't have a 5 doombringers 30 mins in, he only feeds.
My proposition is that someone create mod that posts X (determined by user) amount of times a warn message that comes up in Red stating the player's name and EM % in the chat. The EM% minimum is determined by the person using the mod.
A bonus would be for the mod to just auto kick EM players above the minimum.
