I like spellsword or mageblade, too. While I know one of the appeals of the word that rhymes with dish is that it's short and only one syllable, "barbarian," "paladin," and "sorcerer" are not exactly short words, either.
I knew things had progressed beyond the point of sanity when Noonan himself used the word - and words like "weaksauce." Even if WoW elements do end up in 4e because of their usefulness in design, can't we please leave all of the WoW lingo out of it?
Amen. As a cultural term used by former illithid slaves on the Astral, it's damn cool. But not as a generic term for any random fighter/wizard, and not once the CO board got a hold of it.
In the past in my campaign I've called them "Myrmidon". I'd really like to have some natural, historical something for that class option (like paladin, ranger, witch, etc.) None of the sword-mage, battle-sorcerer, spell-sword hyphenated/compound words do it for me.
And I'd call the thing we're trying to get rid of as "the word that rhymes with fish", because that's definitely what I think of when I read it, completely with stinky smell, ugh.
