I can understand your frustration. A reverse thing happened to me yesterday. I joined leveling roulette as tank because i am doing those for tank mounts, and i got lv 67 dungeon. We had a SCH, who had "The Legend" title, which if you don't know for clearing Ultimate Coil of Bahamut. And our BLM had all diamond gear set, which is for clearing savage.

Anyway, we started. This BLM didn't use any of enmity control actions, aka diversion, lucid dreaming etc. I am used to go into dps stance as a tank while tanking so i did it, but BLM didn't use ANY of enmity actions and at the last boss i had to go into tank stance.

As for SCH, let's just say we wiped 4 times. He didn't use any shields, he didn't use his fairy properly. He tried to spam physick while i was in holmgang waiting for some lustrates... He was so terrible, i couldn't even understand. Without his legend title, i would have thought he was new to the game tbh. (And btw it was a regular pull, i didn't pull 2 stacks or anything because i tried it and we wiped ofc).

I didn't complain. Why? Because they would probably kick me because what do i know right? I am a BLM, SCH, WHM main. I never cleared savage but i know how to not snap agro from tanks and how to properly heal.

People are dicks. I suggest get used to it, because there are a lot of them in this game.
