Cassie has to use a different midscreen combo which leads to less damage, sometimes Spec Ops can't even backdash because she burns her stamina all day. Spending 1 bar of stamina is a big nope for some characters you know, their complaint is reasonable
What you said is basically false, she can do his normal combos after a backdash. After backdashing the second hit of exnutpunch the stamina recovers in time to do this (and other options of course):
Hollywood: backdash second hit of nutpunch, 212d+2+4 flipkick, run, 212, b12 nutpunch. 30%
Brawler: backdash second hit of nutpunch, same combo, into scoop, 32%.
No idea about Spec Ops, never used it. But you can do the same combo except the ender, which would probably be substituted by a missile setup or something.
EVEN if you had not full stamina when Cage does the exnutpunch, you can do backdash, launcher, regular dash d4~special to get a meterless combo as an answer for Cage reversal, for example.
You know fisticuffs Cage most of the times has f3 as only option to punish many things, and after that he can only go for f34 (shit damage), crap f3~exforceball, or f3~nutpunch (low damage and not hitconfirmable and full punish if mistimed.) or f3~exnutpunch (spend a bar to punish, not hitconfirm and full punish if mistimed)...?
That really IS struggle punishing. I wish I had strings as b12 or 212d+2+4 to safely hitconfirm into huge combos.
These complaints about exnutpunch need to stop. Maybe cancels characters have more troubles with bakcdash and punish technique, but anyway, they have more advantages. That's not a reason to nerf exnutpunch.
