Ah yes, the complaints thread
I think one can get used to the jump, but maybe this would be a good time to change it to a more simple jetpack as it doesn't seem to add anything special to gameplay and the jetpack would be much more accessible to new players. Unless fr1tz has anything special in mind with that jump or if there was a technical reason for it being like it is.
One could implement a dodge movement though, similar to UT2004 etc.
I personally dislike that the weapons try to mimic real ones in look but not in function, e.g. they should just be some sort of sci-fi boom sticks as that would make more sense.
I also think the look of the maps could be much more interesting
