Since you want to try to insult me, would be good to do a character search and see the T13 clears I have. I'm the kind of person who goes and helps you, but you do have to be able to help yourself and not stand in every AoE and blame the heals for not prioritizing you over the tank, and thats just normal dungeon running.
The majority of people playing this game are not ready for even SCoB, nerfed as it is. Being wary of randoms doing FCoB after seeing people failing content from 2.2 or earlier is not unreasonable
