I mean to be fair Maeka, I like having it myself from what little I've played of PLD. But I'm also someone that likes Shield Bash(Make it do more), and thinks Divine Veil is weird(Useless solo, just an AoE blunter for everyone but you?).

But much like Shield bash(RIP), if everything is goine fine you shouldn't need it. Yes you can do some neat saves with it but if the Healers are on point you shouldn't have to use it, or possibly the content will end up in a wipe even with that extra bit of healing so why bother.

IT's why I call it a Crutch. At lower levels of skill and nerves, it could be useful if the Healer is in the middle of a panic. As a WHM myself, I dislike seeing it go out before or after I popped healing but also I'm aware PLD have a good heal so unless they are in a state where one hit will kill them I move to other people first for healing. Or I heal them as they heal me/someone else. It's a nice thing to see when a PLD helps out when I'm in the middle of juggling a bunch of people's HP bars.

But to a more skilled Tank and Healer, they're probably aware that at the damage/differculty they are at Clemency isn't going to be as helpful. And the Healer has enough skill to not panic and get the healing out no problem. So why does this button exist outside of niche cases at this level?

Now this isn't to talk down to you or anything, I have no idea what level you play at. Just my own thoughts; I find Clemency to be more useful with randos and non savage content than I do with Premades/raid groups and the tougher fights.
