Wow, I am surprised that people responded so quickly, thank you.
I think I have to consider why I wanted to play those priests. Basically, I wanted to CC as a priest, I guess for RP purposes. I got caught up in Pillar of Faith and Confusion and Gaze of the Adragan, etc. and thought maybe it would work. Reading what you have written and looking over priest, I'm realizing that Priests... don't CC. Not really. There's a few options, but it's not the kind of thing you can build arround. They Debuff much better than I expected, though, as even the comments here made about Wael focus on a debuff (Arkemyr's Wonderous Torment).
So I think Im'a have to decide on two options:
1. Take the Aedyrean Clergy background and play a Wizard or Cipher (although Cipher seems restrictive to me since I have to focus some time on hitting things and can't take talents like Aspirant's mark, since that's a loss in action economy). Then, I'd have the CC and debuffing I want... and be good at using a Rod in PoE I.... AND have summons/charm, while still being a "priest". Maybe I can use scrolls for healing (I didn't want to be the primary healer anyway, just have it as an option). I heard there are Wael-focused robes and rod or something that increases Illusion PLs anyway, which would be better used by a class that... ya know.... actually has illusions as major spell keywords.
2. Give up the CC and just be really good at debuffs. In my mind, I think I mostly just wanted to support a party offensively (debuffs, CC, pet distractions) as a priest, anyway. I could choose either subclass then, although while it's true that Berath doesn't have as cool options as Wael, they are mostly things I want anyway (Holy Meditation, Divine Terror, Salvation of Time) with some bonus debuffs (Spreading Plague, Rusted Armor).
Thank you for commenting. You have helped me greatly, as I feel I have a better understanding of class capabilities after reading your comments. It's really helping me make a decision more easily.
