The moments where I wanted a better close range option was during moments where I'd get hung up on an obstacle for a second and all the melee guys would catch up to me. I don't think it needs a dash or dodge necessarily since it seems like you're going for more realistic movement than giant mechas boosting all over the place like in my Japanese animes. I think just something to recover from minor fuckups like bumping into obstacles would be good enough
For missiles, I think just a bit of proximity burst would make them a lot better, having to be pretty precise when aiming takes away a bit of the crowd control aspect imo
For the fixed camera, I didn't notice it was in the game until I was going through the control options after playing for a bit. Probably not worth cluttering the UI with a popup about it or something, but other people might not know it's there
