Dude, homogenization is bad. They already homogenized the shit out of the healing classes already. As it is, almost every healing class has the same spells with different graphics, and slightly different mechanics. They all have 3 single target heals (fast inefficient, slow efficient, and slow throughput). It's the same with the AoE healing spells. They're basically the same two spells, a spell that drops on the ground for people to stand in, and spamable AoE spell.
I'm sorry, but I have every single healing spell bound, and actively use them all except holy nova and renew, and even then I still use them enough to keep them bound. I dunno, maybe I'm just one of the few priests who aren't lazy. The large spell selection is why I keep coming back to my priest to heal. Let's face it, priests have always been the -THE BEST- healing class because of our utility and niche spells. And rightly so because we are the only class that has two healing trees.
I won't mind if HN is going to replace PoH, so long as it gets a MASSIVE BUFF. They need to drop the damage component, massively increase the healing and range to atleast 30 yards. Ony of my favorite things about disc used to be its increadible mobility, and a buffed HN would bring that back.
I'd gladly give up PoH if they gave us an AoE shield-only spell though. Make it a cast time spell that puts a medium shield (no heal) that affects x players. It would greatly
