I know it wasn't directed to me but!
1: I actually do and Paladins do use a lot of tp, so do warriors, but they usually stop at half since they don't want to use all of their tp. I actually use tactician a lot in dungeons. It does make a difference but barely. And if dps really don't know how to aoe without just blowing out all of their tp+invigorate, lousy tp regen will not help them (this includes goad AND tactician, they can not outlast aoe spam that uses tp AT ALL)
2: Less damage is good, using something that barely does it, other than steroidbole, is not really worth it. And you shouldn't hold a really buffed up bole just for that Tank buster. Fights usually have more than one and you just holding bole for that cases still makes you play with less cards in the end. As i said, you have essential dignity, which works FINE with tanks getting a little more damage and no tank will just die on a buster if they do what THEY have to do. Also: Sch just use excog, they don't need to heal, WHm just use tetra. Just essential+Abenefic them, you have an instant heal with Regen/shield on it
3: Yeah i did, on all 3 healers, in 24 mans where i ressed more than my team while also keeping them alive. And you know what. Try getting a super ewer in that case other than you holding on to it just in case it happened to justify never using a lot of cards because you always needed to have that super ewer ready. WHat do i do? Lightspeed+Lucid dreaming if both are off cooldown and i extend those 2. Works fine usually. I know other asts rarely extend their lightspeed/lucid for some reason but i always do it given the chance(with cards of course). But if dps always think they have to instantly die before you can heal them even if you tell them to wait with actions till they get healed, they can wait before wasting my mp even more. And if fights have an enrage, if everybody dies left and right, it's usually just a lost cause if they just die again after you use lb3.(not in content where you are overgeared as hell and can go make a sandwich in the meantime)
4: I do like Spear/arrow because they at least do something, i like making blms go fast.
It's still so niche uses where it implies that your co healer does absolutely nothing and can't just thin air/Lucid/Aetherflow/Lightspeed for a little recovery in case they died themself. Most healers need only 1 heal to heal a tank after tankbusters, too and mitigating damage is still GOOD. But you can do it on demand and not rng your way around it to justify uses for aoe boles, which have their potency reduced, too. And using superboles is just a waste too.
On a fun note, i always make fun of how i become a resbot in case i need to res a lot.
