So...
Anyone else notice that thing Lucario does where he'll just...
...keeeeeeep on chargin' that Aura Sphere? Like, forever? Until you get close or hit him?
I haven't noticed it with Mewtwo and Shadow Ball, but that doesn't mean it's not there. Lucario, though, will stand there and charge Aura Sphere forever, regardless of you charging up some kill-potential projectile just a few yards out of his range. Approaching will generally cause him to do something, although I don't think this is always the case. Can't tell you how many times he's started charging that Aura Sphere and I've been able to back off, charge Shadow Ball or the Charge Shot, then kill him with it.
Might be something to look into; though I have to commend the entire team on their amazing skill with making the AI much scarier than before, especially as I have no one above casual level to play with.
