If a DPS pulls the mob I will refuse to heal them as its not their job to pull. Will also refuse to raise people who are constantly dying to simple mechanics or not following what is being said. As for commends, I also refuse to commend a silent tank when everyone else says hello. May be a stupid reason to some but I am social and kind for the most part, if I can't even get a hello from you (unless the DPS are just awful) you can kiss my commend goodbye xD
