I just wanted to add my opinion to the Lucario discussion a bit back.
He's a very annoying character to fight against if you only play melee. Trying to get in with weak moves like fighting games usually doesn't work because you can just auto CC any jab and get free punishes off of them, hell even spaced ones you can SDI+CC into them for a grab. Lucario laughs at this and just side-bs you for it, so the correct response is as SB said; SDI. But instead of down and towards, up and away from the weak hits. It means Lucario can throw out more weak, quick moves than any other character in the game to attempt hit confirms and have actual "mix-ups" on shielding opponents. But that's what he was designed to do to make him an original character that wasn't defensive like his brawl variant, so gj.
Still think Wario is the worst character in the game. Falcon also seems kinda bad, and Charizard is looking worse as me+my friends play the game a bit more. Still no opinion on Pit/ Lucas, but Wolf has jumped TREMENDOUSLY on my list of viable characters.
**** Sonic. He shouldn't be allowed in this game. I have yet to play him and I won't really let my friends touch him, but he seems to be a mindless piece of bull**** that does what he wants. And the sad thing is, he might not even be that good. His design should not be allowed in anything resembling melee.
