I can't believe they're even considering bringing back "caster level." One of the things that I have been praising 5e for is not having caster level. Why should a high elf of one class get more benefit from his cantrip racial feature than a high elf of another class? Cantrips scale because if they didn't they'd be useless at higher levels. Why is it okay to them for those spells to become useless for some characters? Why wouldn't a rogue be able to spend just as much time practicing the one cantrip he knows as a wizard who needs to practice dozens of spells?
It's far from a dealbreaker for me but I agree...
Character level and monster level (or just "level") is what spells can better be based on. We don't need a separate token in the game, and caster level would only work in a negative sense i.e. to reduce the effects of spells compared to what they would if character level was used.
There is already still the old problem that a multiclass spellcaster will lag behind in terms of general spells level, and we don't know yet if a half-Wizard/half-Fighter character for example would be balanced against a full-Wizard and a full-Fighter. Caster level makes this even worse... I don't think that in 3ed using character level (house rule) rather than caster level solved the main problem, but at least it's better.
