Metaknight should not be banned.
Logically speaking of course. Pro-ban Arguments are usually subjective.
Show me a completely logical, rational, non subjective counterpoint to the former sentence. =D Plz?
*rolls up sleeves*
The primary issue with Metaknight's presence within the game comes from the fact that he does indeed cause harm to the counterpick system.
This game relies more heavily on a counterpicking system in order to ensure that there is no perfectly safe choice.
Mk has no disadvantages machup wise. At worst, it is an even matchup and those have tuned out to be considered somewhat debatable.
No stage hurts Metaknight, certainly they do benefit the other characters, but MK's capabilities more than allow him to keep up with the advantages provided by those characters.
Often we hear beatability is the issue, this is not necessarily true. Being beatable ==over centralizing.
You can have a character who is beatable like HD Akuma, but still be ban worthy based on the over centralizing issue.
Due to MK being the safest choice at all times (note i did not say best), the game over centralizes around him. Why choose DDD when you risk running into the IC's or Olimar?
Why use Snake when you have someone like Olimar awaiting you.
Why use Marth when there is DDD and Snake.
Why use DK when DDD ***** him?
Why use anyone right off the start of the match? Its much too risky and does not go along with the play to win ideal.
So you pick MK.
As a a result, your opponent also picks MK because he wants to remain safe.
As a result, win or lose, either side would lose.
For one, if you don't choose MK and your opponent does, and you do not happen to be a snake user, even though the match up is certainly beatable, you have to rely more heavily on your skill than your opponent.
If you win, the opponent can stay MK, and considering the amount of tools available, it becomes a more difficult fight. Even if you strike the worst stage for the character you are using, you will still be taken to a stage where you do not have as much of an advantage or is the next worst stage.
So while MK is necessarily broken and is certainly beatable his impact on the game centralizes around him, because he is so incredibly safe, he does not have to worry.
This cannot be compared to Yun who goes 6-4 and 5-5 with Ken.
Primarily because the stages do NOT have any effect on gameplay. You are not interacting with platforms and ledges or borders.
This only further complicates the issue in regards to facing MK, so you go MK, so that you do not lose to anyone else.
Now why is it people do not go MK more often? Simpl because there is a stigma attached. I personally HATE MK, i would NEVER use him, a character who is perfectly safe, without any reasonable weakness that can be exploited reasonably? It does not fit well with me.
Other's may be pressured into not using him, otherwise, we would see alot more MK's in tournaments and see a greater amount of dominance.
Now there are the examples of All and NL and Fiction who ahve beaten MK users like m2k. We cannot forget that these players are all human, subject to making errors, subject to all the variables that life offers. As such, the usage of these arguments cannot be used as direct evidence,it can be used to say it is possibly neutral, but cannot be used directly without also remembering the characters capabilities.
I tried. Go ahead an refute as you will, I won't defend since its really not something I am into right now.
