When I’m a tank, I’ll usualy commend a healer.

When I’m a healer, the DPS who gets my commend is the DPS I *didn’t* notice. If I didn’t notice you, it’s because you were where you were supposed to be doing what you were supposed to be doing.

When I’m a DPS, I’ll usually commend whoever partners with me on mechanics (dodges, tethers, buffs, or whatever else).
