I'm wondering since sometimes I get comms as DPS even in runs where I felt that the Tank and Healer went above and beyond. Which is weird as I don't feel that I did anything to stand out in those occurrences. I just hit things really hard until they were dead and I stayed out of AoEs when I'm DPS.
So what is your criteria for you to decide to give Comms to a DPS over the Tank/Healer which usually are the default choices?
