But you're ignoring Brand's burst, which would heal him for way more with the current WotA than mine (between 224 and 364  health, almost instantly). Grouping the healing per ability cast would also severely limit the regen, but in any case I think it'd be interesting to see what Brand could do with greater sustain. The point to the above changes is to make spell vamp more interesting in general, so I don't think it's a bad thing if WotA becomes a more interesting option on Brand.
