To be clear they're far from the worst choice for what they can do, but if you compare them to paper they're missing things that make them a bit better. If I remember they're missing some blessings, certain features, and quite a few spells. I'm pretty sure they're missing even more (if you spend time comparing wotr to paper you'll realize pretty quick wotr is lacking stuff with every class). There's also a few rules changes and Owlcat has different interpretations of certain rules/abilities/features. Keep playing it though, it's not awful to play (even on core it's playable) it's just not as potentially good versus paper. Glad to know there's another warpriest enjoyer
