1. No, it doesn't. You still need the moment-to-moment gameplay to be able to win.
2. How so?
3. Fighting games always revolve around a single mechanic.
4. Balance issues are present in every fighting game.
5. Just don't miss - that's skill-based. Not seeing an issue here.
6. All fighting games have one way to win.
Since I'm not seeing any good point, please go on.
1) The moment-to-moment gameplay becomes irrelevant if you miss with a Special. If I spend a solid thirty seconds bodying someone, it does nothing for my score or my chances of actually landing a Special on them. Functionally, if my Special misses, all the skilled play I demonstrated was useless.
2) This ties into point 1, but here goes: In any fighting game worth a damned, every single mistake matters. Your loss isn't the result of one mistake, it's the result of several mistakes in conjunction with one another. Every single hit you take
matters. This is not the case in PSABR.
Because all that matters are the Specials, there's no steady increase in pace as a fight progresses. There's no pressuring a weaker opponent, no surprising a stronger opponent. The pace is an all or nothing "Someone has a special? Shit shit shit" or "Nobody has a special. Meh." with nothing in between.
3) Very few fighting games center themselves around a single core mechanic. What PSABR has essentially done is taken a decent fighter and then made it so only one type of move does damage. Imagine if the only way to hurt someone in SFIV was with Super Moves, if everything else just built meter. Imagine if the only way to damage someone in KOF13 was throws, or if only punches in TTT2 caused damage.
I honestly can't think of a single fighting game released recently, outside of Divekick, which is so fundamentally centered on a single mechanic. Stripping the player of options strips the game of depth.
4) Of course they are. But when you've got a game already centered around just one mechanic for actually securing victory, imbalance between characters regarding that mechanic is greatly enhanced, because the Specials are all that matter.
5) That's not a response to the design flaw in the slightest.
6) Bullshit, unless you count "causing damage" as one way.
