No commendations

[Avatre]

but the explanation is REALLY visible and easily noticed whereas a DPSer in tunnel vision because we already wiped once to that add may not realize who is tanking it so long as it's not them.

Yes, and no. I've had to res the entire alliance, as RDM, to avoid wiping, and still got no comms. I've done absolutely no healing/ressing(while it was still needed, I just didn't), and gotten 3 comms. It really is random, as you said, but there is no rhyme or reason to how people choose(I personally give my comm to the person who either died the least, or saved us the most...rarely do I not give out a comm).
