Clearly infinite boost with the right advanced boosters has been eliminated, which is slightly annoying to me personally since I’m a planet dweller, and that used to help a lot. 
Can still tap space to infinite boost but that’s a pain.
I’ve done some testing and both Normal heavy and Epic heavy go to the same height with 4 advanced jetpack boosters installed, but isnt Epic armour supposed to be superior to standard heavy armour in all areas? Even with nothing installed they hit the same height :L
