Tank pulls too much and dies or loses aggro: "Jeez you suck tank come on pick up your slack"
Healer doesn't heal enough and everyone dies as a result: "Jeez healer can you please do your job already?"
DPS doesn't do enough damage so fights take three times as long to finish: "Jeez guys stop criticising me you bunch of elitists lmao you expect me to play perfect like you no lifers?"
