The explanation in D&D for why sorcerers are charisma-based is pretty silly.
Why does having a magic bloodline give you the ability to cast magic through the force of your personality?
Warlock does that much better. Their magic is literally negotiated.
Honestly, you should let any player play any caster class as intelligence or strength-based if they want to.
You should let your players play intelligence-based fighters and barbarians and rogues.
You should let your players play charisma-based clerics.
You should let your players play wisdom-based bards.
D&D needs at least one strength-based caster, and at one fewer charisma-based caster.
Solution?
Swole warlock.
