Dash = Glitch
and dont you come saying that it isnt, why arent those that can bouncing like the rest of the characters?(long time since i played melee, so i might be wrong)
anyway, yes, Brawl could be improved MUCH more considering they removed much that should have stayed, like for example now, short hopping. They didnt need to remove it completely, just nerf it down a bit. Marios spin, why the hell turn it into a Dair? does anyone actually use the fludd? or his Dair not for that matter? okay, his Dair wasnt the best in Melee either, but anyway. "Do not destroy what can be fixed"
They didn't remove short hop. its just not as useful now that they took out L canceling (Since most moves leave you with landing lag that you cant get out of) and alot of the chars have high shorthops that you need to have awkward timing to hit shorter characters (Capn Falcon, Zamus)
I think by dash you mean Wave Dashing (Though I could be wrong)
Its a glitch, But imo one of my favorite glitches, it creates much faster movement while allowing you to do moves like upsmash without running like in this one.
THe Dash up smash seems more like they're trying to satisfy The wave dashers rather then actually a very necessary move.
As for move changes... theres a bunch I'm not a fan of either...
1) Lucas's Up smash
2) Lucas Up B vs Nesses Up B (Lucas's is stronger and doesn't die when you hit someone while nesses is weaker and dies when you touch someone with it)
3) Donkey Kongs B (Its now a shorthopped move if you want to make it go distance, which is cool and and all.... but still takes away from making DK an Easy char... )
4) Diddy Kongs Bananas (WTF?!?!? SO ANNOYING!!!! I HATE THOSE THINGS, I'll slip on one, then caught on another and unable to get out in levels where theres corners.... And then people say don't attack.... WTF am i supposed to do? Sit back and wait for diddy to stop being a little punk?)
5) Snakes moveset.... everythings rediculous.... up tilt, for tilt, a combo, d tilt, >.>.... his smashes are more a hinderence then helpful, except for the Mortar slide and Down smash... sometimes....
I can't think of any other peoples moves... But yeah...
This game has its ups and downs... I love it though... But I hope they make the next game freindly to noobs and experts instead of just one or the other.
