You know the real reason why I think 'gish' doesn't gain traction with a lot of people to be the name of the fighter/wizard comboclass? It's not that it's supposed to be specific to the githyanki... it's really just because it's kind of a dumb looking and dumb sounding word.
'Gish' is like a bad Star Wars race name, not a cool class identifier.
