I had notes for this too, but I lost them. Bah.
White Lotus Academy
I don't like the approach of most of this. All this modification of ALL your at-wills, instead of making a particular at-will better. I don't know if it's actually unbalanced, it just rubs me the wrong way. Master's Surge I especially don't like - too much scope for unintended side effects when adding "save ends" to ANY encounter power.
Punishing Eye's already been dropped from the Compendium (thanks for the announcement, Wizards!) and we should too. We don't allow Artificers yet anyway.
I don't recall anything I didn't like about the powers, but I'm inclined to vote against the whole article just for simplicity.
Get Familiar
A lot of these familiars use the same wording for resistances as the Book Imp, which I just brought up in the AP thread. Other than that, I don't see any issues.
Ecology of the Deva
It's kind of weird which feats are for Deva only and which are Deva or Deva Heritage. I think I'd be ok with opening up everything that doesn't depend on Memory of a Thousand Lifetimes to Deva Heritage, unless someone can point out something unbalancing.
On the other hand, the stuff that modifies Memory of a Thousand Lifetimes makes an already-great power even better. I thought it was way too good when I saw it in PHB2, but I guess my sense of balance must be severely broken since nobody else seemed to have a problem.
Prince of Frost
Deeper Chill says: "When you spend an action point, make an attack that has the cold keyword." Does that mean as well as the action you get for spending the AP, or does should it be, "When you spend an action point to make an attack..."
