MSGuy: I thought that about DDD at first too. Then I spent some time learning that his forward smash uncharged pretty much autokills at 50%, running A at 80% on an average weight class character. On top of this, he has ranged attacks, a long reach, high priority, amazing recovery, absurd chain throws.
ITP:
I don't deny Olimar can order his pikmin in an absurd number of ways, but I have found most of the time the order isn't too relevant beyond not wanting the white one 90% of the time.
Sheik's lack of killing moves worried me at first, but its not like all her smash moves are bad. The trick is figuring out how you are going to kill, then holding that attack back until it will kill them to avoid diminishing returns. If you don't do that Sheik is definitely where you placed her though.
Fox is similar, but he has a few more ways to kill and can do it earlier (90% pre-smash instead of 110%) with much better ways to ramp damage.
I definitely wouldn't put either above A class, but they definitely belong there, probably bumping down Pika and Kirby with Fox at the top of A class and Sheik in the middle.
Like I said, while neither does anything that breaks the average fundamental rules of the game (ie Marth's sword), they beat the other characters that don't by being better at their fair game than they are and even beat some that do by not caring about those aspects of their game.
Thank you for admitting you were a little biased in your Luigi placing. That being said, right behind DDD and Marth is probably right for him. Definitely better than the rest of the SS class by a long shot.
Basically it comes down to Marth just being far above average at everything and the best at several things, while DDD has a lot of aspects that are just beyond reasonable power levels . Luigi has a bit of both of these, but not enough one way or the other to make him better than those two.
On PT: I always forget how diminishing returns doesn't apply to him. That alone probably just proves me wrong.
In less important discussion, IMO Yoshi << Jiggs. Rollout mind games got about 20 times better this game as its harder to screw up and suicide, which is a least something I can say as a + for her. Yoshi I honestly got nothing good to say.
