I'm just wondering what your explanation for that is? How will having MK make Brawl appear to be a better game, while banning him would make it appear worse?
With MK people are going to see: lots and lots of MKs (obviously)
that will get boring.
On top of that there will likely be quite a bit of timing out, with or without limits to planking. Timeouts happen with other characters too, but if anyone sees it happen repeatedly with Metaknight they're most likely going to instantly lose interest :/
Without Metaknight...well, we don't really know what will happen.
All I know is that when I watch livestreams of large tournaments all I see are MK, MK, MK, MK, Snake, Diddy, MK MK MK.
And if anyone thinks banning a character will make the community look scrubby and anticompetitive, I don't agree. If I saw a game had a character banned I would simply be interested in seeing the reasoning for it, I wouldn't pretend I know enough about the game to say they're scrubs for doing so.
