It's so sad that we have three of the best moves in the game (bair, U Tilt, Grabs) and instead of using those MORE, we're trying to nair to footstool to dash dance just so we can figure out something that won't be practical.
I've got a better idea: half the cast can't stop the combination of bair, U Tilt and grabs thrown out at random intervals. Against the other half, we have to think SOMEWHAT. But then there's the key few where we really have to think, and mindgame them into getting dash attacked.
With all of this in mind, I suggest we continue doing what we do best: follow Gates's flow chart. It's the best guide on all of smash boards.
It's not like we'll discover something near as cool as el autobus combo:

EDIT: This was a joke post, I think if we could find a reliable way to footstool people so we can then combo into dash attacks or smashes, I think DDD will be AWESOME.
