Is using Regen a bad practice for end game contents?

Not as a priority but if I am topped off to 90 - 100% health instead of doing nothing, why not re-apply stoneskin.

This is 8 man groups I am talking about where you almost always have a bard and mp song.

6 of one half a dozen of the other... I could be doing something else with that cast time... esuna, dps, whatever... and then just using cure and maybe getting cure 2 procs.

Maybe I am dodging AoEs...

Unless there is a severe damage spike coming, I just don't see the point when I can just cure after and fish for procs. I will SS if there is a big spike coming.

But I just came across a thread where a WHM says regen is useless and he never use it because it may generate unnecessary aggro from over-healing.

If you're talking about the post that I'm thinking of, you should probably just disregard anything that person says about Regen. They admitted that they never once used it for dungeons or HM Primals, so no wonder they've never seen it be useful.

I'll put it this way: in a HM Ifrit run, two WHMs can pop Divine Seal and throw a regen on the tank. For the next 20 seconds, those WHMs can do whatever the hell they want to do (dance sprightly for Ifrit, sprint in circles, run up and melee Ifrit, etc). At the end of those 20 seconds, the tank will likely still be at or above 80% HP and both healers will still be 7th and 8th on the boss's emnity list. Regen as its own skill doesn't generate unnecessary amounts of aggro. Regen, like every other skill we have, only generates excessive aggro when used improperly.
