Vote kick them. You have 2 confirmation windows on before accepting especially when its story mode operation queues to see that you are queued as wrong spec
This precisely. But for some two windows clearly showing their role still aren't enough, or the infuriating "i'm a dps but I queued tank cause it's faster and I want to be carried".
Perhaps the system should only allow you to select what role your current spec is capable of, rather than your AC.
