It's great on stages with low-ish platforms like battlefeild where you can hit an opponent either on or falling onto a platform. I know it has crazy lag at the end, and cant hi that far on either side, but when are you using it for that anyways? The hitbox is nearly as big as Lucas himself, so it's kind of hard to miss an opponent above you unless youre playing sonic, cuz hes just like that.
Spyk90, i'd think that the end lag would make you want to use it less in multiplayer lol. When i was playing my friend yesterday, who owns brawl, it worked well on stages like battlefeild, defino, and the halberd. i would agree with you on certain stages, like fd, as there are no platorms to hit through, but it still is a nice smash overall.
When i played my friends pit, it was especially usefull because pit, with his multiple jumps, he was in the air a lot, so i used it a few times when he was at higher damages. i guess the same thing may apply to peach and MK. accualy, when i think about it, it would **** peach, since she would be in range most of the time during her float, and if she decides to start higher for floating to stay away form it, she wouldnt be able to attack you effectively.
