Is the meta your in heavy with Curse type Warlocks? I look at this book and reading between the lines that is my take away.
I see things here that I have never seen before with a Wizard of any flavor: Psylocks? What is there purpose?
You need: a Hawkeye to boost your Arcane Zap, A zone attack spell for zones, a fire based attack spell or two (Druid/Necromancer/General utility).
I do like the focus in the Air school spells though. Let us know how well this book works for you.
