Which is why we have separate subclasses. And there are many classification systemsBut what is dabbled and what is focused matter.
What is happening here is that you are trying to smoosh two axes of Gish together; Synergistic Vs Dabblers and Primary Casters Vs Primary Hitters. Your three categories make about as much sense as declaring the important alignments to be LG, LE, and Chaotic.
No one is saying "the focus and the dabble don't matter". But they are subcategories of "focused dabbler". If you have a synergystic build what that is matters. And it makes no sense to separate Bladesingers from Echo Knights and when you aren't separating Rune Knights from One D&D Archfey Bladelocks.When the Focus and the Dabble don't matter, the game likely hasn't defined them and has a very high chance of OPness, brokeness, and lack of flavor.
And "I want to be a full wizard and dabble with a sword" is the number one example of this.Gishes are popular because of the choice. If the choice is irrelevant then it's a good chance the person just wants to power game.
There is much much more choice in the synergystic and new builds than there is in the basic dabblers. But I guess where there are actually huge vistas of choice in terms of playstyle and style in general is irrelevant to you?
