Why do you commend DPS?

[dangadget]

I will commend anyone regardless of roles if they do any of the following: they're nice people and don't get salty, they know their job and do well, if they're a new player and listen/ask for help, I like their glamour enough, or they're the last one in the instance. (they still need to do at least mildly well)

This.
Also if they have a clever name
