First off, I honestly have to say I'm STUNNED at the relatively low amount of opposition here. Pre-Brawl attempts to get rid of the name "Ink Drop," before it turned out to not actually be a move at all, were met with more hostility than I care to remember, whereas almost this entire first page is positive responses. Attitudes seem to have changed in the past month or so.
I wholeheartedly agree that a move's name, in most cases, should not refer to its discoverer; it should be descriptive. While gatling doesn't really fit the bill on the descriptive aspect, if there's already a persistence of that term in other games, it seems only natural that it's adopted here, as well. It should NOT, certainly, be named after some random smasher who happened to attend E for All or obtain an import copy of the game early.
If DanteLinkX really did suggest naming it after himself in order to mock the whole ink drop issue... I definitely think that's funny. But if, after doing so, he himself allowed that name to persist, that's just conceited.
In rare cases like the Ken Combo or Wobbling, such names can only be forgiven by remembering that the smashers for which they're named did significant work in discovering and pioneering their use, to a point that it was briefly an iconic trademark of sorts, before its use spread wider in the community.
The name needs changed, my vote's for gatling combo.
