I was thinking about Evocation as being about energy manipulation (I know most Evocations are blasty spells, pretty much any school can be used to harm people as well). Woudln;t it be easier to keep most of the spells where they are while just moving the few which don't make sense where they are? (Eg: Deathward to Abjuration and Banishment to Conjuration would make sense for me.)
