For example: in A12S, there is a lot of healing going on during the intermission with the adds (Almost Holys; healing the tanks from the Time and Might; AOE after the Ultimate is still needed even with tank LB3). Alexander isn't targetable during this time, so it's not uncommon to see healer aggro skyrocket because the tanks can't actively generate aggro on the boss, but healers are still generating it on Alexander's aggro table.
Neo-Exdeath has aggro resets during his fight. While there was a strat to Cover a WHM for the Aero III tankbuster, if you weren't running with a PLD this wasn't possible. WHM aggro was especially bad in Neo and Godka because of aggro resets in the former and the stupid Heartless Archangel overheal to full HP mechanics in the second. Omega M and F also have aggro resets after they split and both appear on the arena (in normal and Savage).
Normal mode A12 also saw aggro issues due to its intermission. It wasn't as healing heavy as Savage but DF healers tended to go a little nuts - as usual. DF healers either don't know how to heal (or deal damage) or they overheal way too much because Medica II is apparently the go-to heal for the smallest bit of damage on someone. I saw many of them get smacked down by him when he came back because they wouldn't cut their hate with Shroud of Saints or Luminiferous Aether. And that's not the fault of the tank either. That's just them being a bad teammate.
Point is, if you have to cut enmity so that you don't die, just do it. Don't be prideful or spiteful because a tank is optimizing outside of tank stance (moot point now, but I still firmly stand behind this point). And this is for any job: healer, caster, melee, or physical ranged. BRD had some crazy aggro generation this last tier, and I would have given anything for Diversion. I managed with timing my Tactician usage (and Refresh at ~22 seconds dumps your opening burst as well as restoring MP for more Foe's); but sometimes it wasn't enough even with good tanks Provoke/Shirking each other. After several dumps I was usually fine, but I rode their butt until after at least 2 or 3 of them.
