But don't you think it stymies offense for some characters? Execution is part of fighting games, and it takes away some importance from scoring a knockdown. I've seen top players mash against me, and while I can't blame them, I consider it dumbing down the game. I'd rather have them have to execute under my pressure than just decide "Okay, I want a dp. GO." They aren't perfect, they will miss sometimes. I had to execute to score that knockdown, they should have to execute to escape.
I'm okay with it because my main has a dive kick that shuts down a lot of junk on wake up, but some people using other characters are frustrated and I can see why. It's a fighting game, but the person on offense trying to keep their offense going is in more danger than the person in a block string if the defensive character has a decent reversal they can mash out. I think you should be rewarded for taking the initiative, not being screwed for attempting a one frame link.
You're right though in that it definitely helps with newer players and I know it helped me while I was learning this game. In tourneys though, it just makes me really salty when I lose because my opponent just was like "mount an offense on knockdown? DP FADC Ultra". It goes against part of what makes SF SF IMO (acronyms ftw). Having that wide reversal window (and such little block stun/low active frames on a ton of normals, but that's another discussion) makes baiting a big part of the meta game and is also why IV is a pretty defense heavy game compared to others. Don't get me wrong, the game is still fun and it's a blast at high level play where there's some more strategy involved, but I think they can do better than what they've done. That's not to say there's anything wrong with mid or low play either - they both serve their purposes and are fun in their own right, I'm mostly talking about tourney play though. I'm not saying make it as hard as III or even II - I still want new players to get into it - but there's a happy medium between those 2 and IV I think they can find. There's good and bad with any system, I'm just kinda venting.
Maybe in SF X Tekken.
