You cannot be more wrong. With all do respect, who are you too preach about this character in the competitive community? What top players have you held your own against that use lucario? How many tourneys have you won with him? What are you contributions? You're spouting nonsense about something you don't understand.
Lucario starts off with the worst damage output in the game, and it gradually grows with power. If you want to make ANYTHING happen with this character you need to learn how to hold onto your stock and live to high percents so that you're character can stay at his fullest for as long as possible. If you "play sloppy" you're going to get KO'd and your character won't be worth jack again.
In order to be even remotely good with lucario you have to have solid DI, careful spacing, and be patient so you can hold onto your stock at high percent for as long as possible. Lucario encourages these fundamentals, not hinders them.
If your arguing that theres no reason to stay in low aura, that's also wrong. Lucario has some of the longest combo's in brawl while he's at low percent, and can literally drag fatties from one edge to the next. Damage why's, they're nothing special, but this also teaches players the value of stage positioning. That's the true reward of his combos. His gimping ability is also a lot stronger at low percent thanks to the reduced knockback of his f-air. So he also teaches how to net early kills at low percent when your smashes just arn't enough.
On top of this as well, we have no clue how smash 4 mechanics will work. Maybe characters will have easier combos or set ups into kills, rendering his aura power up necessary. No one knows, and it's far too early to start speculating and screaming CHEAP as is.
My apologies if i'm coming off as rude, but i'm getting tired of you spouting misinformation about something you don't understand. If someones plays lucario bad that's the players fault. Lucario, more then any other character gets better depending on how good the players fundementals are. If there trash, there lucario will be trash just like any other character.
