Yeah. Not sure if this was simply a matter of getting better with the weapons available of if there was something huge I was missing.
Dunno about the counter, since I abhor the ending lag, but I can kinda see what the uses are for the others. I guess my other issue is how weak he is at 0%. It's like he's a character that requires that you take hits in order to do more damage, as opposed to just trying to go through the match with as little damage as possible. And if you and your opponent are going through a round, racking up damage for each other, and you happen to get knocked out first, then you end up starting on your next life having to try to get your opponent down to however lives you have while being weaker than you were when you were on the verge of KOing them last life. I hate being in that situation as Lucario.
Being down a stock also increases your aura's power. There's nothing wrong with being in the lead with Lucario either, you don't need an aura if you're winning.
