Ah, I remembered some more:
The Menu:I was told that the default menu of Tremulous had been redesigned but is not given in the preview release. I really couldn't tell if this was true or not but I hope it is. If it wasn't, that is my suggestion.
The Gun Reloading:I think the guns should have different types of reloading. I really don't know the extent of doing this in ioQuake3 but let say for instance the shotgun. Why not let it reload bullet by bullet? Giving it a longer full reload time but giving it a quick bullet reload. The mass driver should have a slightly longer reload time and the pulse should have a longer reload time. I can suggest the rifle be given a smaller clip but a much shorter reload time. I'm just guessing as to suggestions so I don't really know how well this would work but it might be interesting and is actually a large role in most FPS games if they give a reload sequence at all (Unreal doesn't give a reload sequence but it is a HUGE role in Left 4 Dead and Call of Duty: Modern Warfare 2).
Gun Models:I remember someone talking about the changing of a few models on the guns. I highly agree with this but I couldn't find anything on the forums... I think I'm missing something but the mass driver I think could easily be replaced with:
http://tremulous.net/forum/index.php?topic=10578.0I also think the shotgun could be given a little makeover since it really doesn't look like much of a shotgun.
Movement Affected by Weapons:If a human is carrying a chaingun, one could imagine that crap being half a ton. One would also think they couldn't sprint all the way across the map with it in world record time, hitting close to the sound barrier. I'm just suggesting this for the chaingun and luci since they're both pretty heavy weapons and they would have they take a bit to much advantage of the dodge effect.
The Tyrant Model: The proposed tyrant model given in the models section looks great and immensely sexy. When will might it be proposed to be placed in game?
