Perhaps the choice of what is available in quick chat is the problem. I do understand that SE is trying to foster good sportsmanship and positive messages with things like Nice Job, Game Match, etc, but since they are used ironically 99% of the time... Even Thanks is a coin toss, sometimes used genuinely, sometimes just as a replacement for Good Match or Nice Job.
Perhaps the only quick chat that should be available are commands that are actually directly linked to the game objectives, like retreat, attack X, LB ready, etc. And at best a Hello only available at the start of the game.
