What is your preference for a player to get a commendation?

If my healer or co-healer is an AST, the odds are very likely that they'll get a comm from me. But that's only if I see them using their cards often and appropriately. I've had a lot of Weeping City runs with absolutely no cards effects on anyone, or stocked in their status bar. As an AST main, I know that RNG can be harsh, but I'd take an AoE Spear over waiting five minutes for an AoE Balance.

Beyond that, if I'm tanking and the DPS pull additional adds or don't burn down what the rest of us are working on, they won't gety comm. If they use their support abilities and play their job exceedingly well (high damage, dodge AoEs, use LB at opportune moments) then they'll easily get my comm. Likewise, for healers, if you have 90% of your MP for the whole dungeon and I haven't seen you toss out single damaging spell, no comm. If I feel your contribution to our progress in a fight (which is pretty obvious) then you're up for a comm.
