Need help / advice for this tank roulette situation

[Fyce]

says you
nothing keeps anyone else from pulling enemies and then moving them towards the tank who can easily pick those enemies up with 1 (one) AOE aside from the tank's ego

If the tank is a second or two late, you're dead. If the healer can't keep up with the added enemies for whatever reason, you're dead. If the healer throws a heal at you because you started getting hit, chances are that the pull will be pretty messy with enemies running everywhere. Early pull during a savage/ultimate, and that's half your health gone in a single auto-attack.

When I said that pulling is not the healer or DPS's job, it goes a bit more indepth that just saying "everyone can pull". It's that you're definitly not well equipped for that task, and that there are so much variables that you don't know about or don't consider that Tanks are, by far, the best suited to engage enemies first.

I recently had a Brayflox Longstop run with a tank having a lot of tankxiety. We were grouped with a NIN that was constantly pulling first, making each pull quite hard to deal with, not even mentionning the lack of AoE damage, or the fact that I was forced to stop DPSing as a healer to save their (not)sorry face. If was pretty stressfull and frustrating for the tank, and we probably lost more time trying to fix everything caused by the NIN than we gained with these pulls.
Let's just say that this experience didn't help with the tankxiety.

You can pull as a healer/DPS. But these roles aren't designed to deal with the consequences of pulling.
And if you can't handle the consequences of pulling without putting the burden on someone else (the tank having to catch up, or the healer getting aggro for saving you), then simply don't do it.
