Ok be honest...

How to get comm:
1) say "first time" in everything even when it not your first time
2) play female miqote or aura with slootglam
3) never dps, make sure you're keeping the other party members at 100% health 100% of the time
It makes your Tank feel safe and the DPS think "wow such a great healer, I could stand in the fire like a moron as usual and they kept me alive, not like those grumpy dps healers who refuse to heal!"

I don't lie about it being my first time, I play an Au Ra though it's 50/50 as to whether my glam is particularly revealing and I play in the exact opposite style to what you suggest and I get a ton of comms.

My boyfriend technically started playing before me but he's done mostly DRG and WAR and I think at this point I have around 7x what he does, though admittedly in the last few months he has played far less than I have.

I think the best way to get comms is to just say literally anything in chat. I always give a "hiya o/" at the start and a "thanks guys!" at the end and that alone seems to get me some. I'd also say if you manage to give helpful advice that can sometimes pan out well, also taking responsibility for your mistakes. I have typed out a quick "sorry, my bad!" during a hardcasted raise and walked out with like 5 comms when nothing else of note happened.

Overall I think it's just about making people like you. They're already inclined to like you because during most fights you are literally saving their lives multiple times, throw a little social interaction on top and you're gold.

To answer the initial question... I suppose? Generally only when I feel I have done something particularly comm-worthy. I had a Final Steps of Faith the other day where the SCH just couldn't keep herself alive so I legitimately solo healed it. I waited for the cutscene watchers to be out for that one. Got 4 comms too. I know how annoying it is to recognize someone going above and beyind during a fight only to have them leave like instantly and be unable to comm them, not trying to do that to people. If it's business as usual though I tend to leave pretty quick.

I don't wait around much anymore after loot rolls are done, regardless of what job role I am. Though I do still toss out commends myself unless I absolutely feel that literally no one in the party deserves one.

The reason for this is because I'm sitting at well over 7000+ commends right now, and I really don't need any more then that. So I generally consider leaving ASAP so that the commends can go to those who still need them for the achievements. That said... the loot rolls don't always go through quickly. So I'm still standing there giving players plenty of opportunity to commend me if they want. And while I don't get as much as I used to due to me leaving as soon as loot rolls are done, I still get them from time to time.

I'm pretty sure at least 1/4th of my commends received come from my avatar simply being a female Miqo'te who I aimed to have an "elegant and beautiful" type of glamour appearance for my healer roles. Course, I've walked away with a bunch of commends on my Tank roles too. And sometimes even my DPS roles. (My MNK got two commends this week for my weekly Lighthouse 24 man run actually)

It makes your Tank feel safe and the DPS think "wow such a great healer, I could stand in the fire like a moron as usual and they kept me alive, not like those grumpy dps healers who refuse to heal!"

With the things I've seen with randoms in Duty Finder, this wouldn't surprise me in the least. Meanwhile, when I see DPS standing in the fire, I'm screaming internally at them to get out of the fire already so that I can get back to DPSing. :P
