Spamming Adlo is never warranted, that's horrible advice. There isn't a single situation where you ever need to do that. You can do it to supplement or help where tank cooldowns don't exist, but it's not simply as a re-apply when shields are broken. You'd be OOM even back in ARR or Heavensward if you did the same thing.

If you are talking a dungeon setting even with tanks that forget mitigation cooldowns exists, you should be using Rouse+Whispering Dawn practically on-cooldown every pull, using Lustrate just get to get in safe range as-needed (not this burn all 3 stacks to 100% HP, that's not necessary Embrace can do that). Build the fairy gauge aggressively, and for all mega-pulls you should have enough in the gauge to solely be using Aetherpact while getting DoTs/Bane/AoE damage going to fry the suckers. Your job is to make full use of that gauge, it's mega-potent for any pull. The QoL enhancements make it even more easier to use and if the tank likes to move a bit further away because of AoEs.

Embrace as-a-button (yes you should have this as a spam button), and Physick is your last spam heal if you need it. Like the pull has to be so outrageous that it's going to be ogre if you don't use those two buttons.

I'm sorry, but you can't just justify we need to be able to spam Adlo at 50% cost to keep subpar players alive, the Scholar kit can certainly handle all the mega-pulls possible.
