Tell me why, and I might bite.
I've been a part of plenty of competitive communities: Melee, Brawl, WoW, SC2, Pokemon, MtG, and plenty of outdated or niche other games. I think that qualifies me to have a say on it.
Even the most hyper-competitive games with communities 10x larger and 10x more intense pro gamers are capable of acknowledging imbalance and its negative impact in the game. The Smash community INSISTS on being a major outlier in their complete non-desire to invoke change through rules or mods(the greatest tragedy ever is that the modding community never got into the mainstream).
We were lucky with Melee, the mechanical requirements were high enough that even blatantly overpowered mechanics never had a major impact due to the immensely high skill ceiling they demanded for their employment.
MK, and Brawl in general, has an extremely low mechanical skill ceiling. The metagame is much more like chess than a true fighter. MK forced insane split-edge timings on other characters, and demanded few in return. Because of huge margin for error when fighting non-mk's, a lot of weaker players were winning at the character select screen.
He killed the community, even for melee veterans like myself (I've made more than a few trips along the east coast). I don't care for your intense logical debates about hair-thin fractions of seconds that show that mk is perfectly acceptable character. The fact is that he hemorrhaged players from the community, and the powers that be let him.
The Smash community acted stupidly, and they're reaping their rewards. The MK change will not change anything, but that's not because it was the wrong change to make, but that the extremely poor and narcissistic people who kept him in the game for so long delayed the change long enough for it to be of minimal importance.
I don't believe the smash community will ever really recover, but I certainly know that Brawl is dead and I'm worried about Wii U Smash's ability to resurrect it.
Anyway your opinion is stupid because you won't accept glaring imbalance and believe that it's possible to overcome insane odds. Problem is that MK mains that don't sit idly would never EVER let that happen. Learn more about competitive gamers and be a little less ********.
