The fact that this is even being discussed is a joke. >_>
I have played very good Hilde players both online and offline, mainly using Talim and Lizardman, and not once have I felt that it was impossibly hard to win or extremely unfair, yes even on seesaw (which I always purposely choose when I fight a Hilde in casuals). She just requires a specific approach, and patience.
Hilde on seesaw or whatever other RO stage, Algol, Yoda, Bonus characters, asura dance, all these are not even close to being worthy of a ban.
It sad to see that the people that can't handle these things go screaming "BAN!" rather than learning how to fight them, because they ALL can be dealt with, and won't be affecting the end results of high level tournament play by much.
And them slightly unbalancing the game isn't a good reason to ban them or even put a soft ban, sure they might not be perfectly balanced, but they don't severely imbalance the game either to the point of there being a need to ban. They can all be dealt with.
I agree with everything you've said 110%. In fact I am happy that I am not the only one on that side of the fence.
