I think the point/question was along the lines of what establishes a tier in SFIV. There’s a number of factors at play but it usually boils down to risk vs reward. Some characters like Viper have to take a lot of risks to setup those Ultras. Pretty much everyone who isn’t Rog/Ryu/Sagat/Rufus do. Strict execution is a risk, whether you want to admit it or not. It doesn’t mean that pro players don’t know how to pull off these combos but the point is that the strictness in a combo/link can mean the difference between landing that combo 90% of the time and landing it 99% of the time. That doesn’t seem like much but in a fight someone like Viper will pay heavily for that execution mistake given how little life she has the tradeoff is huge damage given for huge damage taken. The net balance is that a Viper is simply going to have to take more risks and may end up losing more matches based on a few bad guesses or missed execution. Now the bad guess issue is common to everyone (although given how hp varies from character to character it can be more costly for some) but the execution issue isn’t. Ryu doesn’t really have the same issue. Sure, he’s got his share of 1 frame links but they’re not as vital to his game play as they are for other characters. Consequently his execution requirements are more lenient and risk/reward will tend to skew in his favor.
This goes back to what I said earlier. Logically speaking they won’t make the Ultra II as easy to land as Ultra I and if it does combo from moves they’ll probably make it so it doesn’t combo fully (similar to how it works with Cammy). Otherwise you’re making it so that: 1) Ultra I is useless 2) Ultra II is useless or 3) both Ultras are the same and therefore pointless. More than likely you’ll get one setup (not counting off a crumple stun from an FA) similar to how it works for some characters (like say Bison or again Cammy) that’s unreliable and costly to pull off. If that’s what you want then that’s fine. It’s more than most characters have but it’s not such a huge issue since I think the second Ultras for most of these characters will essentially compensate for this. If you want more then you’re kind of wishing Ryu gets bumped from A tier to S tier…
