How fitting

I might be wrong but pld doesn't seem to like the fact that they have to sacrifice dps for heal. Maybe they could have Heal Over Time ability like regen instead since PLD is like Gladiator+WHM. And then GNB could have instant aurora. However at the moment aurora being HOT provide gnb a tool to build more aggro while pulling in dungeon. I'm not sure which way they prefer.

On magical barrier topic. Since barrier is the same because it create extra hp bar it would still be the same when thrill also create extra hp bar.
If you make this barrier only negate magical attack then it could just end up being a gimmick like dark mind.
