If you are performing a finishing move on an opponent (which would mean you are right in front of the opponent) and a Bob-omb suddenly appears in front of you (which would also mean it is in front of your opponent) and you hit it, both of you are dead. Seriously, stop thinking about "me, me, me" when that bomb goes off on you. That bomb went off on your opponent, too.
Also, just because some characters benefit on certain stages does not mean you have to ban them. If you use a character who is on the disadvantage, you adapt and work around the disadvantages. That is what good players do - learn from their mistakes and adapt themselves to whatever the game throws at you. Scrubs remove the random factor because they are not good at dealing with surprises so they make the game easier for them to win.
First off Faster characters already have an advantage with items on. If you don't understand what I mean, I will elaborate.
As for the stage thing. How do I avoid An infinite standing Chain Grab on Shadow Moses from DDD (and don't say casuals would never do this, It's not hard, anyone can do it), where does my skill come in here? Am I suppossed to never get near him and "scrub"ify (purposley handicapping my skill in order to, inthis case, not get chaingrabbed) myself in order to win. I would have to limit any and all approaches, camp, and stall until DDD gets tired of waiting and perfect shielding.
The advantages certain characters have on a stage is more that "be better" some are downright disastourous. And why should i have to learn how to counter characters on their stages (which would inadvertantly force me to use other characters, often whom I don't want to).
I want to use Bowser, but I am going to Shadow Moses against DDD. I would have to switch to Falco, Pit, Link, etc. to not get completely destroyed. But I want to use Bowser. If I were on a regular tourney legel stage, this wouldn't happen, but instead anything I do is countered by DDD and his ridiculous grab rabge.
This stage application works on any of the banned stages with walls. DDD can beat any opponent in Delfino, Shadow Moses, Corneria (which may be counterpick), Hyrule Temple, etc. All of which are banned or counterpick because of DDD's insanely unbeatable advantage (and the only way to beat it is to become a scrub and go through stupidly elaborate measures to not get grabbed)
