I disagree. You’re only looking at Guile and you’re not looking at the big picture here.
Guile’s main problem in SF4 was that, relative to the rest of the cast, he did pretty much NO damage. You would have to play solid as Hell every match cause if you let some of the top tiers get one or two good guesses on you, then they most likely had the lead again. Other than that, he was a solid defensive character with the tools to keep almost everyone at bay.
Now, in Super, his footsies are better cause of the improved hitboxes; his damage is good compared to the rest of the cast; some of his old combos are easier and new combos are possible now due to U2 and changes to multiple moves such as df.hk and backfist. In fact, not only is his damage good compared to the rest of the cast, it’s just better in general when compared to SF4 Guile.
Df.hk is now a viable anti air, which leads to back fist for a good 230 damage. That, along with Guile’s already great anti air normals will really discourage people from jumping. Faster charge time means Guile builds meter even faster now and controls space better, so there’s way less need to use EX Booms in fireball wars, which saves more meter for FADC’ed FK’s to get yourself out of mix ups, which is Guile’s big weak point.
Also, you’re downplaying the importance of Sonic Hurricane. Watch the Fuson vs. Daigo match. After Fuson punished Daigo’s whiffed cr.mk with SH, the whole game changed. Plus, you can punish people’s predictable fireball rhythms with sonic hurricane. Just having it stocked is a game changer in itself.
He’s not the best character, but he’s way better than before. A lot of his bad match ups are even now (Sagat is 5-5 now cause of SH, improved charge time, and Sagat’s damage getting nerfed like crazy), but he still has a hard time against characters like Viper and Akuma. Still, a handful of bad match ups out of 35 characters is better than freaking half the cast being a bad match up like in SF4.
It’s way too early to decide on tiers, but he’s probably going to be mid or high mid. This sounds kind of bad, but in a game that’s as balanced as SSF4 (so far), it seems like damn near everyone in the cast is going to be mid tier, save for a handful of characters that are going to be better, but not way better like in SF4.
