Yeah, I normally like the 1 DM per character, ONLY if they have some kind of EX move that "might as well be a DM anyway" (Like Chin's Counter, or Maxima's EX Vapor Cannon). Normally, everyone has a move that's almost that powerful (and leave an opponent open for combos), but you don't always SEE these things (Who ever see the EX move for Ralf that ends with a pop-up uppercut into the air? Think it's EX Gattling? Though I'd have to use it when I play him, lol.) I'm suprised Athena didn't get the Phoenix Arrow DM as well, but it's probably because it'd be redundant with have an EX version of the normal move anywho...
I guess that's the biggest problem with some characters. Alot of 2nd DMs were just "ex" normal moves in the past!
On Ralf's Jet Upper... I really don't know why he has it, haha. Coming from XII, though, I wanted Ralf to keep it (it's cool, nice AA sometimes, good confirm...), but I wanted clark to get a longer-range kicking command normal, that would let him combo into throws easier. I really like how this Ralf can use special moves in combos, to act like "explosive command normals" now, haha. Similiar to how Kensou's Rekka's might as well be chainable command normals, in a way.
I'd prefer it, now, if Ralf kept the upper, and Clark recieved a new one. I think it's pretty cool that Ralf recieved one, after all these years. He really is almost like a new character...
