For those that give DPS comms after a run... What is your criteria?

[Mimilu]

As a healer, I give the comm to the player who I thought performed the best and/or annoyed me the least during a run.
As a DPS, I generally give it to the other DPS unless I notice they are playing poorly.
As a tank, I just give it to the healer for having to take care of me. >w>()

Naturally, being helpful, friendly, and/or having nice glam increase your odds of getting the comm. Also, if it's your first run and you don't need to be babysat increase it too.
