Think of the last player you remember commin; why did you comm them over the others?

[Tlamila]

Last one was given to the healer who patiently took care of my failing ass during that run in The Burn. I died a few times so I appreciate the patience. I also wanted to comm the dragoon, who for a dragoon stayed exceptionally alive (but then I just returned to the game, maybe now dragoons don't die as often?) and called off the tank on something. But sadly we can only give one, sometimes it's hard to choose.
In general I comm people who at least say hi at the start (if you're not even friendly enough to spend a split second to greet, you don't deserve it) and then who are nice. Playing the job well comes after.
