The real reason why there is "downtime" as Healer
So I've seen this complaint often throughout my years on this game is that Healer has too much downtime if you aren't DPSing cause things "don't hit hard enough". I disagree with this notion. Plenty of things hit hard, us becoming spam heals is not going to fix this.
The actual issue is this: Healers automatic MP recovery + MP recovery tools are so high that of course you have tons of downtime if you aren't DPSing. With MP is given so freely you don't have to conserve all that much for most content and have plenty of space to spam whatever you wish.
What am I saying? I'm saying if there was a MP conserving factor to the job where the MP regen wasn't so high and you had to properly rest or do things to build the MP back up it'd actually solve this issue about downtime.
Do I think this should happen? Ngl no I personally don't cause I kinda like things as they are, but I do point this out as the true cause.
