I'm quite annoyed at myself, because in spite of the fact that Kyurem-B has both been performing for and against me at what I would qualify as a non-Uber level, I can't shake this slight feeling that it should be Uber. I'm really at a loss as to why this is; I'm sure most of you are aware I tend to not like bans in general. I suppose the two root sources of this uneasy feeling I have are a) Kyurem-B's power and b) Kyurem-B's bulk. These two in tandem, while not enough to make it an unstoppable, broken juggernaut, are enough to make it so that Kyurem-B is only going to have trouble firing off at least one attack against a team packed with Fighting- and Dragon-types. Sure, it's hazards weak, but it has relatively few weaknesses and can shrug off a lot of neutral hits without too much difficulty. It has very high damage output, and against a lot of teams it will have opportunities to dish out quite a bit of that damage. But this doesn't make a Pokemon broken. Truthfully, I think Kyurem-B roughly amounts to an improved CB Haxorus. Good and fairly impressive, but not staggering or broken. I don't think this feeling I have can be justified.
Now, just to be clear, I think that, objectively (if it's even possible to be objective about this sort of thing), Kyurem-B should be OU. I wouldn't let this feeling I have interfere with a vote. It's just... unusual I suppose.
