I'm trying to phrase this as rationally as possible and I don't want this to bother anyone.
This MK issue really shows how harmful ninty's refusal to treat you guys like a real competitive community is to the game. Think of any real life competitive event. Pro sports implement rule changes relatively frequently, SF games are re-released and updated frequently, and even the piece movements in chess have changed over centuries. Magic, the most successful trading card game ever, has new sets constantly being released and cards that have proven to be overpowered constantly hitting the ban list. Good games NEED balancing and tweaks over time when good players hunt out the most effective strategies and start to break the game (when a game is broken is always a matter of debate, but it's always once the decision making process needed to win becomes oversimplified and rote).
I'll admit, some games are lucky miracles from the start and turn out rather well (MvC, melee?), but games that don't aren't lost causes and can really shine with help (like Brawl). Nintendo isn't providing it. It might not be necessary yet, but the survival of the long term core brawl community would be helped a lot by adopting something like Balanced Brawl (plus this awful divisive MK ban debacle would also be nicely sidestepped). You'll lose a lot of casual players but a solid community will probably always be there developing the carefully balanced meta.
Two options: play a bad game, ban characters to make it fun again, or play a better game that isn't necessarily what sakurai wanted.
(I understand that there are tons of tournament logistical issues and problems getting sponsors or w/e when you start "hacking" [lol file on SD card > open stage builder > success] your Wiis so uh maybe forget about it.)
