I'm definitely going to fill in a bug report! (Realises that other people noticed that it actually is m/s too).
But please, whatever gets added to the game, fine, I'll just go with it. But for the love and same of this game, don't ever add rotation like in SE!
That being said, well done OP for not asking for it! And with all this being said, on to what was suggested.
Inertia dampeners off? That's the only thing I liked about SE, so a definite yes to that. Faster speed? Not too fast, but 10 m/s at sprint speed seems a lot. Not for flying in space though, there it is a bit slow.
My suggestion? Well, 2.5 m/s for walkingand 6 m/s for sprinting. For flying in space as an astronaut, maybe it could be a percentage of the server max speed? Maybe something like 10% for cruising, and 15% when you use the sprint button?
Reason for 15 and not 20: We don't want astronauts to be faster than ships when we get the thrust changes.
