If attempting to attack 1 good time drops aggro and puts the TEAM at risk who is really being selfish ? Seirously we all get the same opportunity to que as any role . If you want to dps then que as a dps if you want to heal then que as healer if you want to tank then que as tank. The reality is repeat dyng isnt playing optimal it takes less time to do the job kill and move on then to wipe and restart .
