Sorry. Earlier you mentioned a gish should be roughly equal in fighting and casting (maybe I misinterpreted your statement?). So, thus my point that paladins and rangers are better at fighting than casting, and really not equal in the two. An arcane gish would likely be better at fighting (via magic) than casting--similar to paladins and rangers as you pointed out in your last response.I'm kind of confused, now. What do you mean by "fighting?" Do you mean martial combat, or combat in general?
Paladins and Rangers have morphed into gishes really as the editions progressed and are full-on in 5E.
Anyway, I am happy with using MCing to represent such a gish concept, seeing a Fighter/Wizard as a good enough base to build the concept without the need for another class. But, as you said, a true gish in the sense of a paladin/ranger would of this sort would have to have something "extra" to qualify as needing its own class.
