I don't like the addition of purple. Muddles the clarity of things.
Something incredibly important I only see come up once is that Warpriests are surprisingly swift-action starved. I think that lends extremely well to the Reach build, allowing them to cast some spells and maybe use a swift blessing (or standard action blessing and fervor a spell).
It would also be nice to see a build-agnostic look at the Blessings. I think there are some extremely powerful ones I don't see mentioned (like the minor Healing blessing, which no longer requires the use of a prepared cure spell).
You also call the colours different things. neon blue, blue. Purple, neon pink.
Looking forward to seeing what it'll be like when you get it a bit more figured out.
