I hate constitution based casting. I hate it from a lore perspective. I hate it from a mechanical perspective.
Fundamentally "constitution" just has the wrong connotations for me in D&D. I get the appeal of somehow casting at the cost to ones own vital essence, if Sorcerers got an ability to do X extra special magical thing but had to make a con save to avoid necrotic damage from it, I'm fine by that. I also like that Sorcerers are proficient in con saves, since that indicates some sort of advanced control over their health rather than more health.
But D&D constitution is very much about one's mundane health. Lore-wise, someone with a high constitution is someone who exercises regularly and takes their fantasy vitamins. That should not increase their spell save DC. Nor do I like the mechanical incentive to emphasize stats that go cross-purpose to being given a d6 hit die, nor do I like the game balance implications making an already fairly SAD class more so.
If there was an ability score for "innate magical energy" I'd say Sorcerers should use that. In lieu of that, however, I'd say "Charisma", the pure force of personality, is the best match available.
