DPSing as a healer

[Parawill]

I do not mean to derail, but I think it is relevant in the case where only the tank is going above and beyond the bare minimum. If I was the healer, I would contribute my own DPS because being in a level 60 dungeon beyond 35 mins is ridiculous, especially on dated content.

Just had a 75 minutes Saint Mocianne's Arboretum, with only 1 wipe. This is the result in the final boss (image link removed).

They were not new, undergeared and both had plenty of level 60 jobs. It was a level 60 roullette, not a Mentor roullette. I managed to keep myself cool and explain anyway, and be patient enough but I wished both the slowest of deaths in the inside.

I legitimately asked myself how can somebody fuck their gameplay up so bad to reach those levels of sucking, so I changed to my level 51 Bard and had a similar time parse just SPAMMING HEAVY SHOT and nothing else!

So they were not even trying. I don't know if they are trolling or intentionally wasting people time while watching a movie or they are plain brain dead.
This is disrespectful. Please don't be like these people. At least spam 1 button.
