Thinking about how to rework the first 3 levels of Sorcerer. Here is my stab at it.
1st Level
Cantrips Known: 0
Spell Points: 1 + Cha Mod
Chaos Bolt: (S,M) 1d10 (add necrotic and radiant to the list) + Cha. If you expend 1-3 spell points when casting, add that number of d10s to the damage taken. If any d10s match, chose an additional creature in 30' to make a 2nd attack for each match
Living Focus: As a conduit of raw magical energy, you do not need material components when casting a spell unless those components are consumed in the casting.
2nd level
Cantrips Known: 0
Spell Points: 2 + Cha Mod
Spell Choice: Pick 1, 1st level spell from the Arcane spell list. You can cast this spell using 1 Spell Point.
Metamagic: As per 2014 but remove the points for slots mechanics.
Sorcery: Pick one of the following metamagics. This doesn't count against the metamagics you know, and can be used without expending spell points if no other metamagics are used on that spell. Choices: Subtle, Extend, Distant. You gain another sorcery from this list at 11th level.
3rd level
Cantrips Known: 2
Spell Points: 3 + Cha Mod
Subclass: Subclass features including having your chaos bolt always able to do that subclasses damage type
Spell Choice: Pick an additional 1st level spell and 1 2nd level spell from the arcane spell list. These can be cast using the spells level of spell points. You also gain spells from your subclass.
