Banning chain grabbing would solve everything but that will never happen.
Nonono.
Not banning chain grabs would solve everything. The problem here is that there are a plethora of infinites in the game, and MLG selected a small subset of them seemingly at random and decided to make them illegal while all others are deemed fine.
Banning zero to death options is completely unnecessary. Banning every such method would be impossible. So, to be consistent, MLG should be banning none of them.
From a theory point of view, that is my biggest problem with the MLG ruleset. As for practicality, the ledge grab limit rule has the potential to
seriously mess up the tournament.
The biggest problem is that it provides an alternative victory condition: if you can figure out a way to force your opponent to grab the ledge 35 times, you can then win the game by "stalling" yourself. Except in this case, you don't even need to avoid taking hits or even having
ever been in the lead. Just so long as you're still hanging onto your last stock when the timer runs out, you win.
Now, think about this for a bit. What character is really good at zoning his opponent offstage and at the ledge, and might be able to make his opponent need to regrab the ledge a lot? What character is good at stalling out the game?
That's right, this ruleset gives MK a
brand new way to win by stalling that has never been in a BBR recommended ruleset.
35 is a dangerously low LGL; expect it to be abused.
