Not really. I don't see where you seem to get that idea. Most imbalanced fighters have problems with their character line-up. There are plenty of games in which varicoms are present, and the people who choose to use them aren't invincible. If not just for the fact that they're sometimes ridiculously difficult to consistently pull off.
In fact, it just so happens I have an AVI of the World Cyber Games 2003 Capcom vs SNK 2 final match. One of the players uses the C-groove (three super moves, like in Street Fighter Alpha 3 A-ism) and one who uses A-groove (like Street Fighter Alpha 3 V-ism). Guess who wins in the end?
cvs2 is a perfect example of a game slightly screwed by the Custom Combo, out of all the grooves 3 get used and the A groove is one of th ebest.
like cvs2 wasnt screwed as bad as other games that had it. cc's are too hard to balance and too gimmicky imo, i mean you're just building your meter and knocking your opponent up into the air or hit confirming so you can spam a couple moves for massive damage most of the time
like shit like this in SFA3:
http://www.youtube.com/watch?v=UENxaorxtJ0or crap that came from CC's that led to infinites like this:
http://www.youtube.com/watch?v=Vcr0Cl7L0LMcustom combos have yet to be done right, and needlessly overcomplicate the game with massive execution requirements that shut out beginner players neigh completely, and make the people who master it very kickass to the point where with some characters it is dumb to use a non-Custom Combo ISM/Groove. I think that for a new beginning of the Street Fighter franchise, espically when you look at the type of fighters we have now (land massive combos asap is all they are, look at Guilty Gear, Melty Blood, etc? They're massive combo games with tons of features that complicate the game needlessly like Roman Cancel, Burst, and all these features that while kind of original also make the game
just that much harder for beginners to get into. If you have a hard fighting game, new people are going to mainly mash it out and never get better.
for a new beginning I think Capcom has to keep it simple and go back to what made ST great....2-in-1 combos, footsies, corner traps (if its a 2D game), and controlling the field, not super fancy shit land 137 hit combo hey im super cool. go back to a time where if you pulled off a 6 hit combo it was like "whooooah".
now and days a 6 combo is easy shit, i can do a 6 hit combo in melty blood by just hitting simple variations of button A, like c. A or s.A. Thats dumb. Its fancy and over the top but needlessly so. Theres a good reason Super Turbo is still being played in the really really big tournaments worldwide and a lot of games like SFA3 aren't. its simple but strategic, kind of like chess in that regard, and easy for beginners to get into but still has room for people to master stuff.
simple to learn, hard to master
not hard to learn, hard to master
EDIT:
to kind of showcase my point look at these 3 gameplay vids (both top players playing) of ST and Guilty Gear
http://www.youtube.com/watch?v=WHU9vPIQr5YThis is ST, there is a lot of work on getting in on your opponent, zoning, 2-in-1s, footsies, corner traps (espically with O. Sagat)
http://www.youtube.com/watch?v=smmP4UwpDSUThis is MvC2, there is a lot of work on getting in on your opponent like ST, but its
very complicated, with having to manage 3 characters, 3 characters worth of supers, characters going EVERY FUCKING WHERE, and its very difficult for a newbie to learn that crap. Though MvC2 is running pretty strong still.
http://www.youtube.com/watch?v=Lsl14ejGoCsThis is Guilty Gear. you'll notice its super fast, very flashy, and looks cool and is actually probably a bit more fun to watch from a spectator's point of view, but its very crazy, has super high hit combos. its all about the flash. Thats not to say it isn't strategic, its just very complicated and difficult, which is not what the Street Fighter franchise needs at this point espically after 10 years of its fans about ready to give up on it.
just imo, but I dont think they need to release a super complicated game at this point...we need to go back to basics.
edit edit: this was much longer than I wanted it to be.
