The main things about Falcon that irritate me are his bizarre disjoints. Take away or at least severely nerf the disjoints on his jab, dash attack, FSmash, and possibly dash grab (he's not the only one with a ridiculous dash grab though so I'm not as sure about this) and I'd be more or less okay with him. I'd have less complaints, anyway. I still think his power/speed ratio is a little skewed but he really does have an awful disadvantaged state. I just don't like getting hit with invisible punches/shoulders/elbows.
Also, Aerodrome, I think sometimes moves hit shields that wouldn't hit the user. Could be wrong though. Looking forward to seeing more updates on your website, BTW. I visited it for the first time last night. I think you still think Zelda can turn into Sheik though since you listed her archetype as "rushdown."
A few musings on Gunner:
- Default size Gunner's FAir doesn't auto cancel from a low jump which is lame.
- I was messing around with Franklin Badges to see which moves were reflectable and amusingly only FAir of her normals is. FSmash and UAir, despite looking reflectable, are safe and are simply disjoints. A lot of Gunner's specials are reflectable though.
- Up-B 2 has a lot of power to it but is very poor at sweetspotting the ledge from below (it does okay from the side). Might be worth it to just have a boss OoS option though.
- For all those complaining about Din's Fire putting Zelda into freefall, at least the devs are consistent about it. Stealth Burst does the same thing to Gunner.
