Maggan said:I don't know about "must". Are you suggesting that it wasn't used at all after first appearing in first edition Fiend Folio in 1981, and then skyrocketing to prominence only when 3e was released?
I doubt that theory. Unless of course the term "gish" was a prominent term used for describing ftr/wiz PCs when 3e was launched. Which I don't remember at all.
I think it's a combination of two factors:
1) Before 3e, only a small (teeny-tiny?) part of the gaming community was present on-line, meaning that most times a fighter/mage combination was mentioned it was either in person or by actually writing it on paper. When talking, saying fighter/mage isn't all that more difficult than saying gish, and when writing, I suppose most people used the ("official") F/M abbreviation
2) Earlier versions of (A)D&D had very limited multiclass combinations, and (IIRC) half-elves (only) could multiclass as ranger/mages. Other than that fighter was the only class of the warrior group allowed to multiclass, and the only "arcanists" were mages and specialist wizards (well, bard was an arcanist, too, but I can't remember them being allowed in any multiclass combinations -- but then again, it's been awhile since I really looked at my 2e stuff).
D&D 3e radically expanded the multiclass options, allowing for every possible combination. And it's likely the "community" felt the need for one word to describe all those warrior type/arcanist multiclass combinations. Unfortunately, they chose gish

I still call all those combinations fighter/mage, regardless of their actuall components.
Also, is bard a gish by default?
