[Balance] Reduce spell schools to 3 levels - Restricted champion levels to acquire.
So while I find it neat that you can acquire a champion or design a sovereign with multiple spell schools, it is really only viable to ever level one of those schools. No longer are champions and sovereigns reaching upwards of level 20 or 30, in fact I was hard pressed after clearing the entire map almost soley with my sovereign to reach level 14.
Under the assumption that I wanted to level a mage type character it would be extremely unlikely to acquire even four levels of spells in two of those magic schools both due to the random chance of those options appearing and the restriction on character levels. Not to mention leveling up to those schools often provides very little benefit compared to the other available options (evocation or summoning for example). Leveling multiple spell schools is neither viable nor very rewarding for casters. For non caster ironically it works fine.
My suggestion is to reduce the choices to 3 levels of each school, making it much more likely (and worthwhile) to have multiple spell schools. At soveriegn creation you can only spend one point for first level, and that spell level will contain many (or all) of the spells available at 2nd. New spell levels (and maybe schools) do not begin showing up until 5th level and require 'path of the mage'. It might also be possible to limit the final spell level to 8th or 9th level of that character (Or some other unexplored restriction), so we don't have earth elementals rampaging at level 6.
