One of my good friends (and a great coder) quit after only a few matches because he kept getting stuck on stairs and other geometry, which still irks me as well.
That's actually a very good point. Player movement still feels clunky.
Yep. I agree. There are places where you always have to jump, like when getting upper deck in a junker. I don't know about coding, but is it possible to add some kind of automatic movement in such places? Things like climbing a common edge (junker) or a foolproof stairs animation. The game is not about parkour but teamwork and airship madness. If Muse can solve the first one new players could enjoy better the other two.
About the ready up guys and the lonewolves who don't get the teamwork bit, I'd make mandatory to play the tutorials before joining your first match so everyone have a basic understanding of all the mechanics. A lot of impatient players log in, click quick join before even knowing about tutorials, shout "Ready up fags" a couple of times, get stomped, shout a bit more swears to the other players (noobs, fags and idiot team are usual choices) who usually are other novices who get very discouraged to keep playing (In my first match I got so insulted for bouncing our ship from mountain to mountain that I just keep playing because I LOVE steampunk, but I didn't take the helm again in a long time) and ragequit playing in frustration.
I also think
it is essential to have a fourth tutorial about Crewsmanship: Quick orders and commands (It was hard for me to figure out how to use V, appoint a target with B etc...), teamwork, class roles and the importance of stick to them (I've seen a lot of lv1 engineers empty clips and clips harmlessly into the clouds while everything is on fire and the gunner is frantically trying to repair stuff with his hammer).
I also think a gunner should be able to take the guns from any other class as it happens with AIs, the pilot to take the helm, and the engineer hits should have preference over the other classes in cooldown terms ("please, stop hitting the hull with that pipe and go shooting stuff, I really need to repair it with the mallet and yout cooldown doesnt let me to do so... Does he even hear me?"). At least in novice matches.
