I've only recently started to level DPS classes, always been a Tank main, and recently a healer. Generally I'll commend the other DPS if they're friendly, or a sprout to encourage them to keep doing dungeons, etc.

But outside of that, DPS will usually get my commendation if they're using their full arsenal of tools where appropriate. A RDM who has a res ready to go the second someone dies helps the entire group immensely. Anyone willing to mana shift to the healer when appropriate is good, not pulling threat, etc. Occasionally I'll just throw DPS a commendation if I feel like I haven't in a while and I'm not noticing the DPS in particular, which means they're not doing anything wrong at the very least, and that's commendable in itself!

I guess if I had to make a priority list (I don't usually think about it too much so this is helping me figure out how I do it retroactively) it'd go like this:

- Friendly, this one is most important to me. I don't care if you're bad or screw up or even wipe us all that much. It's a DF, things go well, things go bad. Having cool people to chat with makes that stuff not matter.
- Excellent performance. Like I said, utilizing tools, AOE damage where appropriate, helping everything go more smoothly.
- Sprout symbol. Dungeon anxiety can be a big deal for some, or nothing at all to others, I like to encourage people either way, so dungeons feel less intimidating.
- Owning up to mistakes instead of kind of silently ignoring them. I don't need an apology or anything, there's no shame in goofing up. But a quick "My bad" or equivalent lets us know you're aware of what went wrong.

And you can guarantee you never get a commendation from me if you're rude to people for messing up (or in general, obviously, and I mean messing up occasionally, not someone who messed up and got really belligerent) or if you're actively working against the flow of the group. If the tank doesn't feel comfortable going fast, don't force them! If the healer can't keep up, stop pulling 90 things! If you're a DPS and are pulling (excessively, not every once in a while) because you're impatient, you might just skip the no commendation and go straight to the votekick. Not every DF is going to be as smooth as a guild run, so if you want to guarantee a perfect run, run with your friends!
