From my understanding the changes have been (Thus far, some may be just flat-SUPER changes and not Super AE changes), Standing Jabs now not effective against crouchers, reduced hitbox on Jumping Fierce, and a huge recovery period on his Headbutts.
So, the only thing there that’d effect me as much are the Jumping Fierce nerf and the Headbutt issue.
To put some meat on it, the jumping fierce change is pretty big - It was a great AA move and so far people have said the difference is extremely noticeable, so thats a bad thing no matter how you play - With that in mind, Jumping RH is still a solid Normal.
Headbutt nerf only effects me because I absolutely love using HB on TKD’s for crossover//pretend-crossover mindgames and meter building - The change should NOT effect you too many other ways because it’s not meant to be used outside of combos - Yes, we used to adore this as a fireball avoiding/meter builder but Rog isn’t exactly lacking in ways to avoid fireballs without Headbutt, so that just takes adaptation.
The Standing Jab change wouldn’t effect me too much because I rarely ever used it up close and the only time I really mix it in to what I’m doing is if I want to use a FSJab into Headbutt on a standing opponent whom I feel is too far away for a CShort or CJab while getting charge time.
I’m sure SJab will heavily effect games / mathups that emphasised it, such as Sagat/Abel, even Gief to an extend, but it won’t be a horrendous game changer.
Those are just the three nerfs I can think of and if those were the only ones then I can’t see how Rog still wouldn’t be a pretty solid character, especially if you take into consideration that I’m sure he’s not the only character in the roster being changed, possibly for the worse.
