Well warlock already has a nonstandard caster progress, so the mage group already has a proud nail.
My issue is that I don't want the sorcerer to become a fighter/mage hybrid with a monster transformation subtheme. It needs a boost, but slapping medium armor and martial weapons isn't the fix I want. And if this is the design option they went with, I'd want EVERY current sorcerer subclass ported to the wizard ASAP. I don't feel the lunar or wild magic themes fit a fighter/mage class, nor them transforming into... Uh, I don't even know.
Basically, I want the sorcerer, not the magus.
