|The Fourth Horseman|
I found the description in the class section lacking. I hope in the final version that the paragraphs for Champion Powers more clearly point out that the only power you get (without using class feats) is Lay on Hands, and that in order to learn new powers, you'll need to take class feats.
I spent a long time last night looking for some description telling me how many powers I got at each level, and the list of powers that I could choose as a 5th level Paladin.
For that matter, if you're going to make Lay on Hands a spell, then why not just use the Heal spell and dictate that he can only use the single action version or something? Lay on Hands is strictly weaker than the Heal spell, so you're better off using that if you can.
