Alright, this just seems like the regular cocky "all characters are ez this whole game is ez" nonsenese. I'll give you the benefit of the doubt and let you explain it tho, name a few hard to use character froms any fighting games?
Lets see, from Guilty Gear: Eddie, Testament, Venom, (pre Xrd) I-No and Bridget, though given the game's engine and mechanics you could probably say "EVERYONE BUT KY/SOL" and get away with it. Also, no way in fuck would I forget A.B.A. Paying attention to bloodpacks, knockdown meter, self-inflicted damage and having stupid execution, that bitch takes two and a half characters worth of attention and meter micromanagement just to not embarrass yourself.
UNiB - Vatista (not particularly hard, per se, but very awkward), Sion in this game isn't easy either. Byakuya's kind of a bitch too. Undoubtedly Carmine...
I consider like 50%+ of the SF roster to be rather unwieldy but I think that might be more or less because I'm naturally disinclined towards the game. Similar note, absolutely fucking every character in every KoF ever.
I'm trying not to base this entirely on execution and also take into consideration what it takes to actually get the ball rolling with the gameplan. E.g., I don't consider GG's Testament a particularly high execution character but it's entirely possible to just never get your game going. Bridget and Eddie had a similar deal + rage inducing execution. Byakuya in UNiB is of a similar ilk to this. If you don't know just what to do and when to do it, you'll get your shit pushed in short order.
Also wouldn't describe Hakumen or Arakune or Valkenhayn or Mu-12 in BlazBlue to be user-friendly. Mu-12 might be easier on the whole to pick up at a basic level but she needs to be controlled by someone with lots of match-up knowledge to really have any sort of shot, plus all dem character specific combos.
The just-frame oriented style of Yoshimitsu play in SC isn't easy to play either, Setsuka was kinda bullshit with her 8-just-frame-combo nonsense. OH, Lieselotte in Arcana Heart. Shit, Maori in that same game too. Actually, as far as Arcana Heart goes as a whole, I wouldn't fault anyone who finds learning the more obtuse characters in that game to be a generally frustrating as fuck experience.
Melty Blood, I'm not as well versed in, but I remember Arcueid handing my ass back to me in training mode often.
I'll admit to having never even once played Tekken, DoA or Virtua Fighter so I won't speak to that.
Sorry if I don't find the roster for a game targeting an audience of middle school boys to be particularly challenging by and large. Hell I even said in my original post that there were a handful of characters that had actual execution requirements. But no, I'm not going to sit around and mollycoddle anyone who's having trouble playing SonicFox's Wet Dream: The Game and pretend there's a real challenge to be had controlling all but that aforementioned handful of characters. That's why I specified that this game has more characters that are "hard to win with" than "hard to use."
And no, I'm not even a masturbatory executional elitist. There's no cockiness when I say "the game is easy and 85% of the roster is easy." All that time I spent learning bullshit links and FRCs in Guilty Gear, I want it goddamn BACK. If I controlled the genre, absolutely any mouthbreather would be able to make an effective combo happen in any game if they bothered to memorize the input sequence. We're not all jerking off in arcades anymore trying to see whose is bigger. People with actual jobs are gaming now so fighters should handle very easily over all. I like the SoulCalibur model of easy street execution with a few just-frame oriented characters for the people who mistakenly believe anyone gives a shit that they can hit those consistently with all the challenge coming from actively outthinking your opponent, as opposed to just coinflipping them until one of you dies. And this is where the stream of consciousness is starting so the end of this.
My list for "hard to use" would probably look something like Naginata Tanya, the yin-yang Liu Kang, Swarm Queen D'Vorah, Kenjutsu Kenshi (though this is a real fuckin' stretch the more I think about it) and... that's kinda it. I still can't decide if MoS Raiden should go under "hard to use" or "hard to win with."
