There is no rule how someone should play his Char / Job.
None told you to do a Wall to Wall pull.
None told a Healer just to Heal now and then and let DD's / Tanks die over and over again, cause a Rezz is cheaper.
Hate how other Players, play their Job?
Then go Trusts or make your own Party / Raid.
Stop to tell others how to play, that is toxic and we are not in WoW.
You cry cause you had a Dungeon Run which needet 2-5 Minutes longer as normal ... OMG we are all doomed!
