Exactly what i Was going for in the OP. A good multiclass synergizes and therefore becomes more than the sum of its parts. Pala smites and sp being a Prime example of how cons of two classes basically compensate.
New synergies and interactions is what multiclassing is for, resulting in almost game breaking combinations. That is what is for me the most fun aspect about Any classic rpg. Find builds that bend the Intended play almost to the breaking point.
Two classes slapped together is Not even close to what should be the goal of MC.
Think about the divine soul sorcerer conquest Paladin with warcaster and spirit guards.. Too bad
