As a DPS main, I'm sitting on a cool 8830ish comms. I just kinda chill, slap my silly buttons, and do whatever I can do to be greedy/make everything take less time. I have stuff to craft. When I play heals/Tank, the comms don't matter to me since those roles just get them for existing most of the time. There's a satisfaction you get when you get 3+ comms as a selfish dps, not so much when I'm eating a burrito and pressing a heal/mit.
I only comm other DPS if I even bother sticking around to comm. Tanks and healers only get em if I notice they're really good, and if they KEEP THE THING STILL AND LET ME GET MY POSITIONALS/stay in the ground aoes other jobs slap down.
