Right...
So, what happens at level 11 when Paladins get a permant +1/2 spell slot on every single attack they make forever? Does that get balanced out by the monk... in ANY possible way?
And, also, just to be fair and balanced TM, you do understand the fundamental problem with the design, right? Let's assume you are right and every divine smite dealing +2d8 damage is worth the same as the monk getting +1d6+mod (which it isn't, because the monk doesn't get a +6 modifier to their damage), the monk cannot flurry multiple times a turn.
