WoWo's pressure has holes in it though, as in backdashable holes. You can't backdash a follow up to something that's +18 or +21 on block. Yes I know Wonder Woman has good pressure but if you know the holes in it you'll see it isn't the best.
How much chip does staff spin do though? And how much meter does it give you back? You have a constant pressure tool for about 5/6 whole seconds or something like that, WoWo has maybe 2/3 seconds max before you can just backdash or check her out of it. Nightwing's b2 is pretty fast and as you say it leads in to more pressure, which could include cancelling into trait into staff spin.
I can BLOCK staff all day, but getting away from it is a problem as is getting my own pressure started. I'm not saying WoWo sucks or anything like that I'm just saying Nightwing has more plus frames to work with most of the time.
Yeah flip kick just crossing up all the time catches me out a lot, I don't have much NW exp either besides spending a bit of time in practice skimming the frame data and from having played a few of the good Nightwings on here (including you) but if I just know when flip kick tends to cross up I should be fine lol
For the love of god, go into training mode and see what NW can do after those + frames.
You complain about holes and being able to backdash stuff.
Did you forget how godlike WW's B2 is? NW can only punish backdashes in Escrima if the opponent was right next to him.
B2~Trait~Staff Spin has such a huge hole that it can interrupted and punished.
The only "pressure" NW has with B2 is either cancel it into flipkick or not, even canceling it into flipkick is not a viable option against some characters.
His options are very limited after those + frames, just because you have to block a little longer against him doesn't mean his pressure is godlike.
There is too much pushback, he has an extra option when the opponent blocks the last hit of Staff Spin MB low(except for Catwoman).
His Staff Spin does like guaranteed 7% of chip that cannot be pushblocked.
There is no way that you can convince anyone that NW's frametraps/pressure is better than WW's.
