And, as Cheesy did not reply to your post about Brawl Tournaments, I'd like to say that Brawl is a skill-based game. The whole point of tourney bans were to remove RNG from the game and make everything more predictable by limiting people's non-skill options, a goal that is completely different from the one suggested in the thread (increasing number of options that do not force an auto-loss). Imagine if chess tournaments were sometimes played on a 5x5 or a 9x7 grid, and one player had 3 more Queens. That's what Yoshi's Island with Items on was like.
Top 10 players are able to play the the game 'flawlessly' as in without making a mistake (both in ssbb and elements.) Against a player that does not know what they are doing, they will win all the time. if there are no outside variables are introduced and other player also plays perfectly they will always draw. If the RNG is introduced the dead lock maybe broken even if a player is inperfect in his style but just very lucky.

Who cares?
SSBB bans are to remove RNG from the game so that everyone outside of the Top 10 is ranked by skill and everyone inside the Top 10 is ranked by psychological temperance.
Basically, so that every ranking is done in and of the player in respect to other players. Not RNG.
Thus, SSBB bans are completely non-relatable to Elements bans. In fact, anyone who has played an official match for each knows this fact. The banning of all but 5 stages so that players can have a fair fight is completely different from, say, banning Meta-Knight and other Tier-1 characters so that players do not need to choose Tier-1 characters in order to win. In the current meta-game, competitors, have to select from an extremely small variety of decks to prevent automatically losing, and the suggestion aims to fix that.
