So is it wrong of me to think that Elizabeth DM is the only DM in the game that can hit non Counter hit airborne opponents and that it should get fix?
I think it's the only DM in the game that can do it, yeah, but there are other "Anywhere juggles", all taking meter (which means they might as well be DMs..). Those being Hwa's EX dp+k Move (the repeatable Dragon Kick, if I remember right), and Vice's EX DeCide. And both those characters are ones that can do pretty crazy damage with those moves, when used right.
No other one is exactly as spammable as Liz's, though. I think it's be perfectly fine to make Elisabeth's Grand Rafale DM Anywhere juggle on EX DM, normal juggle for normal DM. This would nerf her Air reset game to using more meters, but still let the normal DM land off counter hit CDs and Etincelles.
Oh, and in discussion of balance changes and all, I had a thought. What if Terry's EX Burn Knuckle was given Guard Break properties? It'd give him a save way to get in, and while I don't think it should lead to a free combo close up (that might be too good), I could see it being used from far distance to guard crush & land a free combo, since he could recover right at the end of the move. Similiar to Shen's charge punch. That's give Terry much more ability to safely persue after blowbacks and power geysers / recovery rolls, which people like Andy and K' can already do, without using any meter.
