Well, it not have been the only reason. Have you completed the raid b4? Are you competent? Did you have decent raiding weapons? Does your current class have the ability to create lots of orbs for the team? Are you a "squeeker"? Or a douche? Many factors to consider. If you answered... yes, yes, yes, yes, no, no... then the kick may have been unjustified. However, if your answers vary even once then the boot you deserved.
