Bair is generally used because bair has a faster startup and a long-lasting hitbox. Dair's slow startup and very brief hitbox leaves you very open and vulnerable.Um... is it well-known that if you run off the ledge and dair immediately, you can bounce yourself back onto the level without using a jump? it's pretty useful sometimes, since it allows you to get back on the stage instantly without having to worry about someone exploiting the freaking huge blind spot directly underneath you. Not claiming to have discovered it or anything, just saying...
Faster startup is good for obvious reasons, but the lasting hitbox is what makes bair so much better than dair in this case. Most characters have UpB recoveries that come from below (Marth, Diddy, Luigi, etc.). They won't be predictable with it because they don't want to be gimped. If they have stall options (Marth's Dancing Blade, Peach Float), they'll do whatever's possible to not get gimped. Against good players, you won't know for sure when they'll use their recoveries.
With that in mind, bair maximizes your chances of hitting them out of their recoveries, mostly because the hitbox lasts for so long. On the other hand, you'd have to have perfect timing AND prediction to land a dair.
Most likely juggle-capable opponents with ledge traps. If your opponent can juggle you so that it's better to recover by ledge, can shield well, and knows to stand slightly away from the ledge ready to react, ROB's fuel might be in danger. ROB has a lot of options on the ledge, but they're pretty blockable if your opponent knows your options.GwJumpman said:You still need to be careful. I've been gimped before by almost all the cast. It doesn't matter who they are, if they're good, you need to watch out.
MK and Marth tend to do this a lot...
