I meant Zoning. Spacing was the wrong word, but I tend to forget to use that when talking about 2d fighters.
Any character that does not have intense zoning options is instantly not viable in Blazblue. Arakune, Rachel, and V-13 all have it, and to a smaller extent Jin.
Yet, Mew2King only camps ICs, and Mew2King is the top of the MK world.
m2k is kind of beyond the scope of the debate because he's just smarter than everyone and more knowledgeable about the game than everyone. MK's high level metagame has evolved in to people camping, for the most part. m2k does things that no one else can do honestly...but that just exemplifies my point, m2k can be played many ways, i dont think its true that he's purely a "rush down" character, and I either think that most if not all characters are rush down characters in smash bros or that the term shouldnt be used for this type of game
The design of the characters are not random at all, and many reflect the very basics of fighting game design.
to an extent I was exaggerating by saying they were 'random', there are some patterns of course, but there is a whole lot of random junk that don't make any sense in terms of balance.
DDD is through and through a grappler. His chain grab was intentional ( an otherwise useless waft of air keeps the opponent afloat allowing DDD to chain grab them), he has a huge grab range and a quick grab,as well as his immense Bthrow.
I concede that ddd's grab game is intentionally buff, and this would make sense for his character. But, added onto that are good projectiles, and an amazing air game, which make no sense for a "grappler" character.
also his chaingrab is NOT balanced, its overpowered and you would not find anything comparable intentionally programmed into any serious fighting game. (i highly doubt it was intentionally programmed though...its not a waft of air, its just a random attribute of the move that if you weigh more than a little bit the move doesn't cause you to fall combined with ddd's large grab range)
Jigglypuff was made to be a glass canon, until Brawl came around and they designed her to be more of a gimp based character, which also happened to Mario, as Smash seemed more determined to pull itself away from the typical fighting game types.
Your guess about Jiggs is as good as mine, she's almost the Dan of Smash Bros. now i.e a ****ty character that you only play for cool points. a "gimp" based character is an interesting new archetype, but they should have made it easier in Brawl for bad characters to gimp people if they were going to do that. but again, they weren't going for balance in smash.
And in most fighting game, these same characters, are also hard to balance, mostly because of 0s to death on them or turtling, these same problems still exist in smash.
Even with an infinite throw loop, the grappler of Street Fighter 2 Turbo was one of the worst characters in the game.
Big slow characters are almost always unviable in smashbros, DDD is a huge exception, granted (snake is arguable, but i kind of don't really consider him "slow" if played correctly...which against adds to my point about smash being "unbalanced" lol)
but for every T.Hawk or Hugo theres a Potemkin or Zangief
