Holy only works for about 6 seconds. After that stunning doesnt work, and any aoe of the enemies means you need to move (and potentialy cancel casting). It disrupting the ability for a tank to stun is on that a downside that doesnt matter that much (against big groups as tank you wont control them anyway).

6 seconds against tankier enemies isnt realy that much. Its mostly on outdated content that this feels massively OP. Sure, it saves you 6s from healing, but in the end, since you mostly use oGCD heals. Thats all the time you save. In 6 seconds enemies generaly dont dish out such large values that you suddenly become forced to use GCD heals.

Its ranged, which i think on its own does quite a lot as it means you dont have to dodge any attacks (and that guarantees you finishing casts). And it can also be used while moving when you turn on insta casting. I think this is a decent alternative already.

And dont underestimate the value of it being ranged. If as WHM you have to interupt a single holy, the value of all the stuns barely matters since its still a lost GCD cycle at that point. Being ranged makes this interupt less likely to happen, and that is the value it gives.

For SCH and SGE, while they are instacasts, they dont realy add great benefits, since any enemy aoe already forces you out. Slow and blind wont change anything here. Giving only SGE paralyze and SCH only a blind would instantly benefit the SGE a lot more, since that can actualy interupt a lot of casts of the enemies and still allow you to stand in the danger zone. This makes them significantly weaker than holy and gravity in such effects, but their damage does allow them to be interupted every 5th cast anyway.

1 missed holy cycle takes 140 potency away. Even if gravity does less at 130. If you get interupted once every 10 casts, you are still losing out on damage value.

The problem isnt realy the effects here, its just that its a single button that you spam for all healers. And the same issue that a lot of healer abilities have.
