Commendations are really only there so you can feel good about yourself, outside of the really gaudy rewards for the achievements they are worthless.

That being said I do tend to give them since I usually can omw out of a dungeon even if I race to the exit. Usually I will comm the other dps unless they were just terrible at their job, it will go to a healer that dps during their down times and sometimes I give no one comms if they waste time or are terrible. For instance when I get stuck with a pt of rp ppl that emote and do rp talk the entire way through, generally wasting tons of time along the way. I had a lala healer the other day who didn't need to heal so would just use the cheer emotes on the tank instead of contributing in any other way. Also couldn't kick them since they came in together.

I do not think these players deserve any type of comm or reward so they get none form me.

They need to revamp the system if they want to make them more worthwhile. Make them give better rewards or some sort of buff. Maybe boosted exp for jobs under lvl cap or something if you give and get 3 comms in a row or something. Maybe throw in drops like TT cards or other rando items. 5/5 glamour 10/10 crafting mats, 20/20 furniture, 50/50 a mount or something. Make ppl really want it and work for it.
