I registered for Leveling Roulette as SCH and got Ifrit Normal (lvl 22 something). Got a DRK, SAM and BRD. I thought, this will be a quick and easy one, like always. Everything went smooth until the Infernal Nail appeared. Neither tank nor DPS did anything about it and focused Ifrit. Ofc my own DPS was not enough to bring it down before Ifrit disappeared and casted its enrage. Never happened to me, but okay, there are always first timer.
I wrote in chat to focus down the nail/pillar, and the tank already pulled while I was still typing... just great. Casted protect, and went on to summoning my fairy. Meanwhile the DRK took the flame breath head-on without any CDs at all, next auto hit killed them while I was already casting Physick... swiftcast rez, heal, protect again. SAM in chat: "Uhm, healer?" I explained I didn't had time to summon my fairy, no answer to that. Then Nail phase again... BRD and me focusing on it, but SAM and DRK keeping on Ifrit... wipe again. At this point, I knew I had to approach the SAM more directly and told them to attack the nail/pillar. Their answer: "Your job is to heal, the tank to take damage, and mine is run around and do damage!" SAM was also the only one to take avoidable AOE damage while every other person dodged it.
The BRD said they were attacking the nail. At first I thought they meant me and themselves, but as it turned out they meant themselves and the SAM. I knew from SAM's movement and later checking the battle log that it just wasn't true. Well... you can imagine how our 3rd attempt went... even the DRK was focusing the nail this time, but this SAM...
I was trying to vote kick the SAM, but it got declined. (I should have noticed earlier that both the BRD and SAM were from same server, probably pre-made/friends.)
Then the sh*tstorm started. SAM calling me: "HEALER? YOU C*NT", even the BRD suggested getting rid of this a*sehole (me), cause they really thought it was my fault that we wiped.

In my entire time in FFXIV I have never had to experience this kind of people. I thought, it was the best to keep quiet in chat and just write reports for harassment. Sad thing that this DRK probably thought we wiped because of healer fault, and I wasn't able to give them tips to use CDs, ready checks and countdowns.
