Some suggestions now that I've had a chance to spend some time with Q:
Zelda is definitely OP. Her boxing is phenomenal, and she completely rules from a distance. She has instant mobility with the warp, and her recovery is very safe as long as you can aim. An approaching reflector even allows her to dominate the few characters who might try to fight her from a distance. Why is her boxing so strong when she is clearly designed to be a ranged fighter?
Bowser's armor is really hard to deal with online...maybe it is less of an issue offline. Perhaps the window for teching RRdown could be increased?
Falco's reflector is far too powerful. Not only does it shut down physical approaches, but it also sets up, and is totally safe to throw. It should either only reflect projectiles, or only hit physically (and even then, not drag the opponent back to Falco).
Charizard's upB is insane, and KOs <50% easily...he has too much longevity and power to possess that kind of early kill potential.
ZSS feels good, but she relies very heavily on uTilt spam to start combos. Maybe you could give her more variety by reducing its power and making her throws better setups (even dThrow can be DI'd to a safe distance easily).
Regular Samus power bombs are more or less unusable. Maybe if the hitbox was bigger or the explosion lasted a few extra frames. The new screw attack feels janky, but it works. I think her zAir may still be causing desyncs or even crashes. Missile canceling is hard due to her fall speed, but her improved melee makes up for it.
Snake should be able to do his air dodge grenade thing.
Captain Falcon's knee chaining into itself is ridiculous. Offline, he can 0-death a number of characters quite easily with it out of a chaingrab. Maybe you could make his dThrow techable, since it is so easy to land and follow up on?
Toon Link's boomerang KOing at 150% is not really necessary. He shouldn't be able to poke for KOs when he controls space so well.
Sonic completely destroys a number of characters, yet is destroyed by TL due to the polarizing nature of his high pressure/hitstun game. Maybe he should lose some combo potential in exchange for better KO moves.
DDD is dumb dumb dumb. Waddle Dee command is a cool idea, but the implementation is horrible. They just soak up EVERYTHING, and it makes for alot of horrible matchups.
I actually don't think the faster boxing makes that much of a difference for Link, but I tend to avoid boxing with him as much as possible anyway.
Zelda's not OP. Zelda is shut down hard by good rushdown characters and characters with a solid projectile game. Falco mostly just laughs at her approaching reflector, and Lucario and ROB still give her a nightmare. I also assume DK (or at least Gold_TSG) will zero-death a Zelda they can touch - she's very VERY light. You have to get close, but it's very rewarding.
Did not know you can tech RR - can you tech flying slam too? Armor is annoying but workaroundable (bait it and smack him up).
Falco reflector is fine. It used to meteor smash, and they realized it was too much. It's good, but can be baited hard. It's also Falco's only good ranged attack besides lasers (bair and fsmash are arguably passable). I think it's a good substitute for ftilt in most situations.
Charizard up+B is good, but SDI it if hit with the full thing, or DI carefully, and he's SUPER punishable on landing. I'd need to play Sneak, but I don't think it's an issue, even having played a few other 'zards. The sweetspot is small, and while rewarding, not exactly consistent.
ZSS dthrow you always get guaranteed fair or uair if you follow-up right - you're not doing it right. Or else this an issue specific to Puff or something...
People know my thoughts on Samus, but I will say that Power Bombs (Which she did have in 3.3) are awesome. Play Gold_TSG for a Samus with a good ground AND air game, and he'll show you how he uses them.
Falcon is in a great spot personally, and I don't know about this Snake thing. But Falcon can struggle to get in, so I think it balances out. Also, DI.
TL boomerang is fine - if he's raising you up that high poking for KOs seems fine to me. Also airdodging and don't get hit, it's not a Gandouken or something.
Sonic loses to Sheik nair about as hard as he loses to TL - I don't know about better KO moves for him... he's pressed for KOs but his racking is so good that nair, fsmash, uair, and bair [and his throws] are generally enough.
Dedede is nuts, no idea how they plan to nerf him or buff others to deal with him. His spot is awkward because there aren't that many people who play him very effectively to identify what the problem is or how to fix it.

Super armor on mobile attacks is plain unfair. Imagine if Sonic had super armor on his down B or boost.
Lol Bowser dair, fsmash, RR, GC. But Bowser (Armor on Yoshi's egg would be so dumb - maybe on another attack, but not a bouncing egg).
