"Join red. This match needs to be stacked. I am going for an achievement." -same player, suddenly not so highly regarded.
Muse, we have a problem. Any achievement that turns generally good guys into groinal appendages needs to be tied to a mine and cast off the ship. Treating other players like offal just to get a meaningless number and fluffy bit of virtual swag is simply wrong. Achievements should only reward skill and honor.
