I commend whoever left an impression on me, be it by their name, glamour, attitude, or performance. Just whoever sticks out in my mind at the end of the run for any positive or even neutral reason. I got most of my 3k+ on whm though (then again that is my main). I don't think that tanks or healers should necessarily be the default comm magnets, and I'm noticing an increase in comms on dps as opposed to the former.
