Don't forget how some schools don't benefit their skills. The entire necromancer school is this personified, and the Master skill is the only one that doesn't scale with its parent school. Totem of the Necromancer, the highest level necromancy spell, scales off summoning.
I believe in one of these observations (M.15, after checking) I specifically point out Necromancy as one of the Skills/builds that is a poorly supported option.
I apologize for a lack of updates or additional content, as working on my personal projects for the game has been a little disheartening, and I've been rather busy in meatspace this month.
