since you're not a certain someone who simply gives up before trying, i'll address this.
But I think Hilde crosses the line. Yes, the rest of her movelist is not that impressive, but nobody is considering that as the reason for her ban. Its her charge moves, its her doom combo. At worst, its a REDICULOUSLY POWERFUL combo thats completely safe and guaranteed. At best, its a completely safe INSTANT KILL. The latter point alone is enough reason to seriously consider banning her, but the fact that its a SAFE move is what sends her over the edge. If you didn't know, that's SNK-boss-level cheapness. Even in Guilty Gear, you will have to pay some kind of price for an instant kill move!
there's a lot of stuff in this game that's ro instant-kill, of which also happens to be safe on block: kilik's fotd to asura can be broken but that doesn't lead to anything, and it ro's from the middle of a large ring stage. yoshi can imcf into several different kinds of ro options (including this:

a

a as you can get more than one 44bb in a juggle. that being said, how easy is it to punish imcf? furthermore, how easy is imcf to implement into one's game given how fast it is? that's pretty good for a move that's, what, i9? lol.
the difference is that people haven't gotten abused by such things yet. hilde is easy to abuse if you let her abuse you, and the problem is that people are still frozen when they get locked down and they stop thinking and start panicking.
don't even use ceirn's regionals vids as a basis for banning. there were so many things he utilized that people who are familiar with hilde would never fall for (c3a blocked into c3b and actually having it hit? be real... that should hit rarely at best and should take several attempts to set up). the problem is people are viewing these cali regional vids and thinking "omg, if these really good players are losing to hilde, then it must be broken!" either that, or the players, although good, hadn't dealt with that kind of character and style and couldn't adjust.
Really, if this was present in any other game, ANY other game, she would be immediately banned. VF, SF, GG, even friggin Tekken! Only because of the history of this community is this topic even up for discussion.
i'm sorry, but i'm calling bullshit on the one game i'm more than familiar with that you listed (the rest i have no idea). i've been playing in tournaments for tekken since t3 and not once has a character ever been banned. the only character who wasn't was jinpachi in t5:dr, but he was made with the intention of being ultimately superior and he was on a level of akuma st broken. consider the characters in past tekkens that were simply badass: ttt/t3 mishimas, ttt ogres, ttt changs, t4 jin, t4 steve, t5 steve, t5 nina, t5 bryan... none of those characters, although way hardcore, were never banned.
The only way to avoid being in ANY sort of disadvantage, damage or not, is to hope she whiffs, which is completely laughable!
again, that's bullshit. firstly, you can step the move. but you know what... let's even say you're not good at stepping and say you're forced to block it. what's wrong with blocking the move and being forced to block again? the worst she can do is make you block
another move. you're acting like "omg, i have to block this move, and then i have to block another one!? that's broken!" not really. yea, it's good on frames, but as long as you block there's nothing she's really going to do to hurt you. at that point she has to charge it again before she can ever use it. after then she's stuck not being able to use any b attacks or throws.
also, let's say you
know that hilde is charging her b, but can't use it yet. what's stopping you from being sneaky and using a b throw? if she breaks it she just screwed up her charge, if she gets hit she's on the ground and is most probably in close range (not her forte). plus, she may have tried to break the throw and still lost her charge in the process.
The only people who actually think that's a logical answer are people who probably shouldn't be playing this game!
no, the people who have a logical answer are the ones who
should be playing this game because they know there's a way around everything. nothing in this game is
that broken that it can't be danced around one way or another. just because you haven't figured out that "sometimes a good defense is a good offense," doesn't mean that other people haven't.
Why should I have to stand 30 feet back to avoid a simple combo?
why the hell don't you try to bait the move and rush her down so she can't get breathing room to abuse that crap? why not block and make her use the rest of her movelist? why not try different things? who's fault is that?
Why does she have +frames on block?
because namco made it that way.
Some may say use 8wr to get away, but that is not always successful, as its not completely safe since the moves are not 100% linear, so even then, its low risk/high reward for the hilde player.
it's only a high reward if you let it hit you. blocking it nullifies a lot.
i'm going to tell you a story of what i deal with here in japan in explaining why she isn't broken and finish up from there. i'm not being scathing, nor am i being patronizing. just read and try to learn something from it.
the japanese players i've played against are much more defensive than american players i've played against. what i've begun to notice is that the better players instantly turn their game into turtling when i pick hilde. they won't attack until they know they find an opening. they'll block 3 or 4 charges in a row before coming in for an attack, and they make sure i don't get an opportunity to use any charges after that.
if i do get a chance, they instantly go back into turtle mode and wait, yet again, for their chance to attack.
when this happens i'm forced to use hilde's other options. that becomes difficult because her other options... aren't that hot. her lows are really telegraphed to the trained eye (aside from 1k_2k), and her throw range could be better. i then use those regular moves to open up options for my charges. however, her other moves are crap for damage and they leave much to be desired with their obvious holes (1kk isn't safe, nor is ws a+b or 33_99k. the last hit of 3ba and 6bbb can be ducked. her long range movelist, outside of charges, doesn't track worth shit) . she has a really,
really hard time knocking down a life bar when her charges are simply getting blocked. if i can't start opening up her charge options, i'll probably lose.
the problem with the vids of american players i've seen is that people seem to just forget that there's a thing called "patience". everyone seems so eager to attack hilde that they don't think about what they're doing and they just do it. if you play that way then you deserve to lose. it really makes shit seem broken when you don't know how to handle it; but, you got a brain... use it. it's not impossible to get around, trust me. i've seen people deal with it, and i can as well.
