Ok be honest...

[Gemina]

Are you kidding? Everyone is already gone from the instance before I can even finish saying, "thanks for the party everyone! And grats on the clear new peeps! Hope I did OK. BTW, if you wouldn't mind passing on that minion, that would be super cool. Oh and...."

Maybe I should write a macro for farewells haha!

I primarily look to give my comms to DPS based off their performance as healers/tanks are bound to receive the comms just for being their role, regardless if they're good or not. The DPS that made the run overall faster, helped explain things, or made use of their utility deserve the love, too. Otherwise I don't really give my commendations out otherwise other than maybe the healer if they, again, made the run overall faster.

It honestly just depends. There are so many factors and depends if people just want to give them out. This coming from a guy who has 4820 or on his main and 540 on his alt. (Yes I do probs play this game a bit much.) I myself do always try to give out comms, even if some of the times its to the undeserving.

[Kaabi]

It really depends, if a run was nice and went well I'll linger a bit, but also to give out comms myself. If it was god-awful I'll leave the moment I can >__> Unless I saved all of their asses and low-key expect some praise in the form of digital shoulder pats, I don't want to spend a second more in there!
Also, for some reason I notice people give out comms in the easy-as-heck guildhests (yay for getting lucky in Mentor Roulette \o/). I mean, I appreciate them, but me just spamming stone and maybe 1 cure to kill that armour guy... is that really commendable?

[Besame]

Mostly on Bard, over 1000 coms in a little over 2 yrs. Did potd, H on H and select or HAVE to do dungeons for loot, tomes or MSQ.

No, i don't stick around for commendations. I sometimes stick around for other reasons, such as talking a bit to people. But i handle commendations differently than most. In my view commendations are not for people who played well, but for those who were fun to play with, which usually requires them to do some chatting. But since hardly anyone ever writes in the chat apart from "hello" at the beginning and "gg" at the end (and when there was a conversation, in most cases it was i who started it), i only rarely give out commendations.

my first 700 comms came from my Drg performance, around 500 from Smn and Brd, and from tanking and healing over 6000 with a grand total of 7766. War and Sch main i stance dance, dps, and mitigate damage well. i usually dont say shit to no one but 0/ speed run everything making sure my heal is comfortable in dpsing with minimal healing. i usually get three comms from 4man, i always comm heals when i tank unless they dont dps in which i comm a Dps and when i Dps i only comm another Dps or Heal. i have received 5 to 7 comms from 8man and 24man when i use to torture myself in duty finder Ex Primals in 2.0, 3.0, and old to new 24man. I always comm ppl on thier performance with the occasionally slip, i dont care for chatter unless your funny or you need help with a mechanic or rotation, to many ppl are not funny but lame when they tell jokes.

So I recently hit the 3k and think the reward is a little underwhelming - a palette swapped Fat Chocobo doesn't really do it for me. Should have checked the reward out first.
Was expecting something a bit more 'parade-y'. First World problems, eh?
(also i'm under no allusions that playing a healer-full time got me there much quicker than if i'd been a DPS)

[Dogempire]

I do stick around for about 5 seconds in case for comms or if I want to comm someone.

Though I usually give the healer a commendation because I know how hard it is playing one sometimes. Other than that if I see a summoner/red mage resurrecting someone, tanks being overall extremely sturdy for some reason, something else that stands out, or they're a male that flirts with me and I'm desperate, I'll give them a commendation.

By the time I remember that commendations are a thing and I'm supposed to commend someone they've already left.
