I may not understand everything, but I do have much better understanding by comparison
If you knew more about how much bias and repetition OS has you wouldn't think that. It's like negative campaign ads where all you see is bad things about a president without seeing the good things, it is eventually going to make people (at least stupid people who don't do research on the whole subject) unfairly biased.
I use DDD occasionally in friendlies, but he's so much more boring. It's too much grab, bair, and fair. Sure I use every move, but it's just not as fun to me. To me MK is fun, since he can attack you a lot. DDD is less fun by comparison. That is 1 big reason.
I actually DON'T think he should be banned, even when I mained DDD. Even if I was never allowed to use MK but had to fight MKs, I wouldn't mind just using Snake or DDD against them, and have done well much in the past. I even beat chililns MK 2-0 in tourney with snake at CH4, despite that being the 2nd tourney match I ever used snake in before, and putting like 3 hours into the character. Snake does well vs MK. I think banning him is stupid, he is a fun character to play by comparison to his competition. Falco and DDD are too heavily reliant on CGs, camping, and bairs/dairs. To me it gets really boring. Motar slides with snake aren't that good on people anymore, and snake's game besides that is just camping. That gets boring. Attacking disadvantages me too much for me to want to often ever do it. Pit would be fun except that attack power deterioration HIGHLY encorages arrow camping, which is extremely boring to do, at least to me. Rob is too camping reliant. Olimar is too camping reliant. Not much is left but Diddy, but since I'm not good with projectile/glide tossing, I can't use him properly/well. You can think MK = no fun, but I have more fun fighting MK than I do vs a Falco or any projectile-camping-character or someone that just tries to be gay to you the whole time.
ledge camping is unfun. Plank won 2 tourney sets over eggm because of ledge camping, sheik vs falco. King and Forward also think ledge camping with jiggs is broken. GW can do it fine in brawl too. It is just unfun. Fighting people is fun, and for the exception of Tornado (which you just have to block), fighting MK is fun. Disagree if you want, but MK is much more fun to fight than Falco/projectilecampers to me, as well as to use.
