Check the HDR section at shoryuken, it's probably buried pretty deep. HDRemix Akuma was banned because he still destroyed everyone with an option no Turbo character is supposed to have, a 100% safe jumpin, and Turbo players didn't want to deal with a massively dominating force being added to what was just supposed to be played as another version of Turbo. The guy trying to get him banned, a former (and present) Zangief player also manned up and proved his **** and beat some dominators like Justin Wong to argue a case to get him banned.
That seems to be the case.
I don't want to derail this thread with the Akuma topic, but it is eerie how similar the discussions at SRK and Sirlin.net are to the discussions we've had here. Reading through their arguments was just like reading through one of the old "Ban MK" polls, except with significantly more profanity and less 12 years old posting "I canz bbeet him wif my Cap Falcun, so he is obv not broke".
Apparently Sirlin approves of the EVO ban.
Some interesting parallels I found:
-Character is unanimously agreed upon as the best in the game.
-Character has advantage over most other characters, goes even with a few, and has only one possible disadvantaged match-up. (Some claim it to be a 40-60 disadvantage, many others claim it to be 50-50, and some maintain that it is, in fact, 60-40 or worse.)
-Character is not solely responsible for making any other character non-viable. Most seem to agree that his best match-ups are ~70-30? Any characters that he does maul were already screwed anyway.
-Possesses incredibly safe options for all situations.
One interesting difference, however, is that HDR Akuma has
not dominated any major tournaments in the way that MK has. That is to say, Akuma has never swept the Top 8 (taking, say, 5 or more of the top 8 spots) of a large, national tournament. This is, apparently, because at whatever large tournaments have been held, the top Akuma players purposefully chose not to use him in the main tournament. I couldn't find any statements about why they did so, although the EVO decision was apparently partially based on this "fishy behavior". Speculation about their motives is pretty plentiful. Apparently Akuma is also banned from money matches at many HDR tournaments, but not the main tourney itself. More "fishy behavior".
Many people in their community are unhappy with the EVO decision, just like many people here are unhappy with this discussion.
Still, it's important to remember that none of that provides outright justification for a MK ban in and of itself. There are similarities, true, but MK is not Akuma, and Brawl is not HDR. Whatever is best for Brawl should be the guiding factor here; not what others have done. I only posted this because numerous people have sporadically referenced Street Fighter and Akuma all throughout this debate, so I thought this information would be interesting to some people here. If it isn't relevant, feel free to remove it. (Or ask me to do so.)
