In response, I'd like to highlight that you do agree that MK is certainly not unbeatable or broken. Rather, he has a very low learning curve with high reward. Not to mention his popularity has progressed his metagame rapidly, more so than every other character in the game.
However, let's face it. You are on the boards because you play brawl competitively, enter tournaments for money, and hopefully have fun trying to win. If we treat brawl as a competitive fighting game, we must acknowledge that there will be a dominant character. Only rarely do we find that the difference between tiers of characters is small.
I personally do not believe MK has an advantage over every character, and that there are several that can take sets of MK when both players are of equal calibur. We often forget that the best players do flock to the best character, but again, I repeat that MK being the best character does not mean he is broken, which I think is the one and only criteria a character must reach to deserve the ban hammer.
As far as Xyro's argument concerning Brawl as a counterpick game, we must analyze our current ruleset(s). Stages with walls or walk-offs are banned because of D3. Large stages are banned because of potential stalling. Hazardous stages are banned because we are afraid of the stage having too much influence. If you haven't gotten the picture yet, our ruleset is already detrimental to Xyro's image of a counterpick system. Even Green Greens, his favorite stage, is banned at his own tournaments.
Perhaps you should look at the bigger picture if you want to ban MK with counterpicking as your reasoning. Look more at alternatives, such as having a wider stage selection, enforcing stage striking for first match, allowing 2 bans per set, etc. to really advocate the counterpick system brawl has the potential to have.
If you're worried about MK stalling once gaining the percent lead, perhaps a new ruling on time is in order. Clearly, ledge grab rules do not work. I can stall anyone out with MK with having maybe 20 ledge grabs only, depending on the stage. (Possibly less on BF, definitely less on SV, etc.) Perhaps if you remove the time, then call over a TO if excessive stalling is occurring, less complaints on planking/scrooging will occur. If you haven't realized this either, time is an advantage for MK in nearly all scenarios because of his campy tactics.
These are only examples of course. I just find that banning a character for the wrong reasons, and especially when no right reason exists yet is... wrong. Instead, there are alternative ways into making Brawl a better competitive game. Like attacking the source of planking (the timer) or addressing the viability of characters (stage selection.)
I hope you have considered all of this before choosing a pro-ban status. If you have, then by all means stand by your decision.
