I think the movement speed is fine. As for crafting, I usually never bother with it in games, so I like it that they made it something that's fun to experiment with. The devs have also stated that the co-op experience is going to get a drastic overhaul, and I personally haven't experienced any connection issues so far. If you equipped Scarlett with something and she's running around in her underwear it's because the texture isn't in in the game yet.
Things I do agree with: stealing is too easy for characters with zero points in Sneaking and Lockpicking. Ice outside of combat is funny at first but gets really annoying if you slip four times in a row, they should at least let you get back up faster. Finally, I see no reason for there not to be a shared coin purse in single-player, it's annoying if you happen to talk to a vendor with the character that doesn't have much money. With the drop-in style of multiplayer, it might be hard to program this, though.
