I'm writing this because I've always heard about it, but it never happened to me until now. I was doing roulettes, the level 50-60-70-80 dungeons and we get Grand Cosmos. I'm leveling dragoon and in the team we have a level 90 gunbreaker, level 90 astrologian and a 81 level sprout dancer doing this to proceed with MSQ. We reach the final boss all good, and then the astrologian for some reason refuses to engage with any mechanic of the boss. We wipe 3 times in a row because he died instantly and couldn't heal the tank and us from the AOE's and the fires.
I and the gunbreaker explained all the mechanics to him, he said "Ok" and dies immediately again on next pull. I check his search info to see if he is a new player and I notice he has 3 classes levelled to level 90 and multiple others at various levels ranging 60-80.
I believe he was trolling, the sprout understood the mechanics from the first pull because we told him pre-pull, but a level 90 player with multiple classes can't do a single one? We wiped 5+ times in a row because he couldn't survive the first one and because we had no Warrior the tank couldn't heal me or himself to solo.
What are you supposed to do in this case? We vote kicked him after 6 wipes in a row and because he is a healer we waited so long to get a new one that we decided to just abandon duty all together. I just felt sad for the sprout dps that had to wait again in queue because some person just couldn't be bothered to engage with the mechanics. I was afraid to even say anything to him aside from explaining mechanics because I knew I would get reported for being "toxic".
