This is all textbook cases of FATE Grinding Syndrome. basically when all these players do nothing but grind FATES and spam the same spell over and over again. They know nothing about the class they play and blame others for their bullshit.

1: During blayflox's longstop, we had a black mage spam nothing but Blizzard. When I tried to explain the umbral astral mechanic, he told me "White mages don't know how to play black mages, so shut up"

another thing is tanks that cannot tank. they do not hold aggro, they don't pull, and they NEVER mark targets for DPS.

2: Warrior in stone vigil doesn't mark and runs in before I Protect. he pulls 5 enemies and dies ahead of us. he immediately calls me the worst healer in the game. then I tell him to mark targets, and he says that marking is stupid and that no one uses that anyway... I may be able to heal mortal wounds, but i can't fix stupid.
