I am not bad. I cannot be bothered to level up.
^^^ thats their problem for trying to be a video game Bada$$.
If they want to appear to be that good, then group them with good players.
Problem is, for example, I have an alt account. My main would be a legacy 4 level something, but my alt is a level 75 with a co-op star, a flat KDR and a negative WLR.
You wouldn't believe how many time this helped abuse matchmaking, even just by level.
