Let me start by talking about how healing reduction works in PvP: it doesn't reduce ability healing or shields—divine benison, adlo, etc., so it is extremely underwhelming. I think this is a smart way to buff SMN because of how much they miasma. Let us look at DRK combo: they do not even use power slash in PvP because souleater value is absurd compared to power slash. DRK was the most balanced tank in the game, but it got a TBN nerf. Power Slash combo as a whole is bad; reworking healing reduction would at least make it worth a little more. It would be a way to slightly increase the skill cap indirectly by giving people more useful options to use—rage of halone on a healer is pretty useless too (not that PLD needs a buff, but if PLD needs a nerf, it could be nerfed in other ways). Cometeor debuff is just WAY better than terminal velocity debuff, and yes, I know that ranged LB is more burst, but cometeor radius is also bigger—consider also that cometeor debuff is 15s, and that tank LB is only 10s now! The tooltips for these say they reduce healing magic potency, so are abilities not healing magic?

For healing increases such as the PvP trait increased healing potency, it at least says it only increases spell-based healing. Now I personally think things like this trait should also increase shields and ability healing potency but then have its percentage reduced to 3% or so instead of 5% to keep it from being too much. Something I would like to point out is that increased spell-based healing and dmg up traits are not increasing SMN bahamut dmg or SCH fairy embrace healing, yet at the same time things like disable or rage of halone do not reduce these untargetable pets' potencies. So I say since SMN is in a weak spot, why not just make it so dmg increases for the SMN affect their pet, but leave it so dmg decreases to the SMN do not reduce bahamut dmg. This change might also make it worth it for SCH to consider using healing trait. SCH is really falling behind in healing to this random, uncoordinated DRG PvE pressure, the WAR vs WAR meta, and the dmg increases last patch. WAR tank stance also doesn't increase ability healing which is bad for SCH because lustrate is its core.

Let's move on to AST: it used to have really niche mitigation by being able to drop a 30s bole, and disable used to reduce LB dmg. They made this change to disable without including it in patch notes, why? Was it so busted that AST could disable LB? It was a thing better players could do, and now that's gone. Was 30s bole busted? I won't address that question, but here is what I will: I believe it's not worth it to use bole now but believe it's better to convert it. I would say I convert about 85% of my boles to lady of crowns. There is still a time I use bole for sure, so don't get me wrong. With what I just said, what good mitigation does AST have now though? 15s ED is unforgiving especially against DRG, so you won't be binding much now.
