The main problem I found was that if you trade with a smash while charged with Lucas you still lose your charge. Also Yoshi fair being weird sometimes.
Lucas feels great. Bair is so much smoother now, Uthrow is really good (Shadic is totally going to nerf it though), PKF is a lot less spammy and there is actually a reason to use it on the ground now (it goes faster/farther), dtilt is amazing.
I just wish dair would ground bounce and I miss the old size of Psi Magnet.
Other bad stuff:
Uthrow/Dthrow might be overpowered, Uthrow kills really early and Dthrow sets up combos REALLY easily. Dsmash still does ridiculous damage, and I think it should last a bit longer (just make it kind of like Link's Usmash where the first two hits are weak and lead into a strong third)
Dtilt is kind of annoying because it sort of just sticks you in place for a while before it starts bouncing you, although it doesn't actually combo into itself much I don't think (it's just easy to get stuck in). Utilt still seems a bit janky but it might just be me.
Other than that I really like him and think he feels solid, good job SHeLL, Specks, and whoever else worked on him.
