For those that give DPS comms after a run... What is your criteria?

[Bright-Flower]

I give comms out at random most of the time. Only when someone really stands out, which is rare for me for good or ill, do I intentionally pick someone.

[Kolsykol]

Maybe people will think this is heresy, but I rarely give comms I only really give them if I feel like someone made a more obvious above average effort.
Partly it's because I quite frankly simply forget too.

I might give DPS a comm if I see them actually using their abilities instead of being lazy, like MNK using Anatman and charging Chakras and doing all their positionals while using True North and Riddle of Earth accordingly, using Mantra when big damage is coming out from the boss and in big pulls etc.
Same with BLM if I see a BLM with really good uptime who is using their arsenal, basically if you're a DPS and I see that you make an actual effort instead of just doing the bare-minimum.
Or a SAM that is actually playing properly, I do notice.

I almost feel like throwing it at NIN's simply for using Trick Attack on CD because quite frankly it feels like almost no NIN's do it's like they just do the first one and then forget that it even exists.
If I notice that they actually do use it on CD I might throw it at them too or if I see them using their teleport last sec to get extra hits in etc.

Edit: The real answer tho is that if you're a friendly person you're 500 times more likely to get it than if you're a shitty person too.
If someone is just especially nice I might give it to them too.

As a healer, I give the comm to the player who I thought performed the best and/or annoyed me the least during a run.
As a DPS, I generally give it to the other DPS unless I notice they are playing poorly.
As a tank, I just give it to the healer for having to take care of me. >w>()

Naturally, being helpful, friendly, and/or having nice glam increase your odds of getting the comm. Also, if it's your first run and you don't need to be babysat increase it too.

Knowing the pain of unappreciated DPS everywhere... I almost always give my comm to fellow dps unless they're especially atrocious in performance or behavior. If tanking or healing I'll still lean toward dps since a fast run was through competent dps 90% of the time.

[Rowde]

I haven't cared about comms in forever. I typically...

If I'm tank, I comm Healer
If I'm Healer, I comm Tank
If I'm DPS, I comm other DPS

People have to do something special to make me deviate from that and lose my comm rather than "earn" my comm.

[NinaTurner]

Typically because I'm the healer and am either playing with a friend who's a tank or because I feel like the dps never gets them and I wanna be nice.

[Escalon]

I main Healer, but give comms to DPS most of the time. Reason being that, just because you are a Tank/Healer, does not mean you earn it by default.

I see a lot of DPS trying their hardest to be good at what they do, they do not get enough recognition for that in my eyes (I play all classes, thou main Healers),
so I'm familiar with DPS classes rotations and skills, and on fight by fight basis I decide who from the 2 to 4 DPS did the best and give the comms to him.

I will give Comms to Healers and Tanks only if they go above and beyond their normal role. Like a PAL off healing when a healer is dead in a Raid, or a GNB gives Heart of Stone to someone just being resurrected so he does not take fatal damage and so on. Same for Healers, I will give you coms if you Pre shield Tank busters, use rescue to help others, etc.

Being bottom of the comm list.

[Eien713]

I'm on console, so I can't really measure a fellow DPS's performance very accurately.
If I feel stuff melting fast, I commend the other DPS and even sometimes praise their performance at the end of the duty.
If they can outDPS my BRD (or gives me a run for my money) while having a not-so-stellar gear, they definitely get a comm.
If I notice them using their different tools well, I commend them.
If they're friendly and aren't atrocious at their job, I give them a comm too.

[van_arn]

If I bother to commend, it's because someone stood out. That could be because I saw an excellent player, or... a remarkable example of the opposite.
