I've been playing B- with a couple friends online, and after a while here's what I think of certain characters. They may not be perfect, or professional or whatnot, but whatever.
Ike is an absolute monster. So far, I consider him one of the best characters in the game. Eruption, despite only seeing about three uses or less per match, is an amazing move. It is one of the best edgeguards in the game, not only because it hits people trying to sweetspot the ledge so easily, but the lingering hitbox hurts them even if they decide to stay on. Using it with aerial quick draw is one of my favorite things to do. Either the enemy spotdodges, leaving them vulnerable, shields, allowing me a shield break, or rolls, which I normally punish by just using it early. I love it. Uair has scored me quite a few surprise kills because of the copter, and Dtilt is actually useful now. I've been using Jab-Jab-Dtilt-Utilt for easy damage, or Jab-Dtilt on the ledge for an easy kill. Not to mention Fair windbox, the complete amazingness of quick draw, and other things.
Ganon is amazing. He wrecks projectile spam with the choke, his dash attack is pure **** on a stick. Fsmash is a very good move, I've used it to edgeguard with quite a bit of success. Although I still don't use Ganon Pawnch often, it's definitely one of the most satisfying moves in the game. I think you've successfully pulled him from his slump to be one of the strongest characters in the game.
There's nothing to say about Captain Falcon except that he is legit awesome. True Sacred Combo, Reverse Sacred Combo, Triple Knee combo on certain characters, his godly speed, the HYESZ, epic taunt, everything about him is absolutely perfect. There is no way you could have pulled him off any better than he is. On top of that, he's quite strong too.
Bowser, like everyone has said, is a mixed bag. I've played one and it can get quite annoying at times. He wrecks characters with lower damage moves, but hard hitters can destroy him. I'm not exaggerating when I say that Ganon's Fsmash is > Bowser. I've managed to triple knee combo him because of his fatness.
Zelda is a spacing goddess now, and I absolutely love using her. When you can kick into a kick, you know you're good. It's always fun spiking enemies from two Bowsers away. While I haven't played Samus much, she overall seems to be quite a strong character, especially that sweetspot Zair. It hurts...a lot. From my experience, all the characters seem quite strong, though. Squirtle and Wario also strike me as currently being very strong, even though Squirtle is getting a nerf as said before. Out of the characters I've seen/played, the two underpowered characters seem to be Metaknight(GASP) and Lucario. I might be wrong, but that's just what I think.
So far, what you've done is amazing. I've had more holycrapthatwashilariouslol moments than any other game. My friend tried to use Bowser's Nair offstage to get my Ike to use a move and gimp myself. I tried to Dtilt him, but the windbox dragged me toward him and I Dair'd him perfectly as he was spiked down to hell. It was so amazing.
Long story short, Brawl Minus is the proest Brawl to exist. Also, I do have a few replays on me, but they're all .bin files. I can upload if you want.
