Oh yeah, a lot of my running around was trying to get Dash dancing down to a tee while fighting xD So I needlessly ran into danger and got smacked for it. Though if you see me going straight for the enemy, I'm usually going for a Power Shield > something, since I know my opponent will try something. If they don't do something, I can jump cancel it and put myself back at neutral and start again. Its either that or I run to shield a move > jump cancel FAir. Since we have so many options out of shield and stuff, I try to treat it like SF 3rd Strike and parry everything I can and retaliate whenever I think I can. It does result in mistiming the shields and unfortunately Dash dancing messes with the timing as well, since it's one other thing to think of xD Also, even if you power shield the smashes, Robin has lingering hitboxes after the initial hit, which does throw me off a bit at points (particularly DSmash which is 1 for sword hit and 1 for the traveling electricity). I love to power shield a little too much xD It depends on the player when I determine the risk behind something; I've fought that particular player since the 3DS version came out, so what seems risky isn't so much for me when I know how he thinks (just as he knows my plans). So I go for them, and sometimes I get punished, other times I land some sweet comebacks. My playstyle is quite risky I can admit, but the way of passive agressive style is play either agro or defensive till something favourable shows up from your opponent's reactions, then exploit it till victory or defeat xD
As for the offstage BAiring, I know I can hit Robin and stage spike him mid recovery, so I kept going for it xD Really, being on the ledge for me isn't scary, so I don't mind going for stuff like this since I can usually get back on without too much grief. Besides, if I don't practice them now, there may be a time I'll need them and I can't deliver xD I'm willing to lose matches as long as I can learn to do the stuff I go for with a bit more efficiency each time I go for them (plus I have gotten those stage spikes repeatedly before, but I don't show those matches since those were one sided d
As for the DB2 up version, that's essentially the ground DB setup I wrote on my guide (Emblem Lord can back up this one, since he's also written a bit on it on his guide too). That small lift is the key to getting the setup to work, as your opponent's next move will determine if they get hurt more or not. Whether your opponent hesitates, throws a bad aerial out, or commits to an air dodge, it gives the opportunity to make them pay for it dearly with tilts, grabs, even smashes. Best thing is that the setups flow into one another, so they're almost like a combo if you can get them all in one go.
Also, glad to hear it helped your game out in some way xD
