A lot of people don't appreciate good Damage Dealers which is wrong. Good damage dealers let you skip multiple phases in extreme boss fights, acknowledge your damage dealers everyone! Give comms to damage dealers who are going out of their way to be the best they can. If you don't do this, your damage dealers will switch to heals or tank because they are not getting recognition for doing a good job(plus it's pretty hard getting the commendation rewards as dps because people don't see them).

There are many times where damage dealers out-perform the tank or the healer in your group. Don't be a sheep and think who is performing the best.
