I once had someone run off the edge on their own in Titan and then went '' FFS HEALERS '' xD...
Also, BLM in Eden's Gate: Resurrection who got really mad at me because I pulled him into safety when the boss was doing that instant kill AoE and he was just standing in the middle and kept casting F4 right as it was about to go off.
He got mad because he lost Enochian ( which was his fault regardless, I main MNK and BLM if that happens just Transpose or whatever... ) and yelled at me then shortly after he backed into the edge and died and started ranting at the healers.

Don't underestimate how desperate some people are to blame everyone else for their own faults.
It's like with people who are assholes, people rarely acknowledge if they're a bad person even people who commit pretty hideous crimes still think they're a good person and will find ways to victimize themselves.
