So much hate

The lack that Regen has is the healing over time. This is a problem with bosses, because the battle is always different from before, which means if anything happens and the tank has regen on, you will take aggroed, while Cure II gets slightly more aggro but all at once, in a moment you can control, when you can say "this is the good moment for a Cure II".
And the problem is even bigger with HM primals, because it seems they have a double aggro bar: the main one, that is always on the tank, and the other unseen one, that doesn't affect the tank, and controls the attacks like Eruption or Weight of the Land.
I noticed that every time I use Regen, I become the favourite target for these attacks, while when I don't use it I almost never get picked. Now I never get picked for these attacks, because I learned not to use Regen, because it's not needed, not even in danger situations. It's just a skill that makes you relax during easy boss fights.

BRD:Oh wait, it seems if I dont use certain skills, I would not get picked, lets lower a bit of DPS and let others take the blame~
DRG:Oh wait, it seems if I dont use certain skills, I would not get picked, lets lower a bit of DPS and let others take the blame~
MNK:Oh wait, it seems if I dont use certain skills, I would not get picked, lets lower a bit of DPS and let others take the blame~

You could start right after begin?

I myself had to also break the habit of throwing on regen... At the wrong time. Using it after the tank establishes hate seems to work fine but it really is a double edged sword in my opinion and like stoneskin you need to know when you shouldn't use it it seems.
