I think Eric's right about the banning thing. No way would they allow a stage that can randomly kill you regardless of your damage. I'm hoping Brawl will let you take out random things like this but that probably won't happen.
No he isn't, the game hasn't even had a public beta and you are already thinking of banning stuff? Melee=/=Brawl. They are more then likely working on items being more balanced (hello mr. exploding random crate of doom that pretty much got items banned) so that Final Smashes can be used...since they seem to be pretty NEW and innovate the gameplay. The only reason a stage should ever be banned is because you can go around in a circle in it forever, I think that if you can't play on a stage cause you are not aware of your environment it is because you do not have enough
skill to overcome the environment. That chimera is fucking huge, probably slow, and very obvious. If you get killed by it, you more than likely deserved it.
Hell, half the stages in Melee that arent banned aren't even neutral stages and favor characters, its not like they just ban stages for some random / favorable elements.
Regardless, how about you wait til more than like....50 people play the game before you start calling bans.
