Wow, that's delayable? Shit! I have a friend who will run that into the GROUND! Can't believe I didn't know that. Then again, my Bruce only has like 5 moves, and one of them isn't even a move...it's a bunch of backdashes.
Man, honestly, anything I have to say about DR Nina is either suspect or generic. I've never fought a super-solid DR Nina.
I just run d/f+4 antics. try to make her use wtf. punish her launchers with f+2 most of the time. (pretty lacking...yes). cancel your dash-ins and block. try to stay in f+3 range so you can duck it, by, in turn, staying in your f,f+2 range.
But...if you don't want to get in there and "fight", just bdc the entire time. :-) When she's obviously annoyed...go smack her around.
His poke pressure is killing me, and EWHF or f+4 kills me trying to come in after 101 BDC's. No good in BDCing all day if you are equal or less in health. Dashing in and blocking just gives them a chance to start their poke nonsense again.. SSing his poking sometimes works, but it feels random on which way evades stuff(example d/f+1<4). At least against Nina you can SS her poking if you can exploit their pattern..
