There is, devine soul sorcerer subclass, and the Teurgh exist in the unearthed...
So tell me, what is the diffrence of a cleric spell doing 10D6 damage or a wizard spell doing 10D6 damage ?...
None. But that is highly disengeous. High level spells do far more than 10d6 damage. And the Divine Soul can only know a miserly total of 13 spells at level 12. The aforementioned cleric/wizard can probably prepare more, from the complete bank of all cleric and all wizard spells in the game, and change them on a long rest.
when you break down the spells in 5e it dosent matter that you can prepare or access more spells, in the grand scope o things, and most classes can do most things regardless, and with alittle tinkering you can access the spells you want with subclasses or through domains...
Sounds like you have never played 5e...
What matters ultimatly is A how mant spells you can cast, B how hard those spells is to resist, and C how many spell effect a round you can create... the later one is a more serious deviation from 5e then having access to more spells, wich in cases is just minimal at best...
What matters is having the right spells known/prepared. It doesn't matter how many fireballs you can cast if your enemies are immune to fire damage.
