we need new models -> there is only 3 models atm, compare to utXXX or q3
, we need more charismatic models
, it will feel better in videos and ingame 
graphical tweaks -> wsw gfx are pretty nice atm, but imho it can be better (maybe adding bump, new sort of textures would be a good thing
(I remember high definition textures from "QuakeWorld retexturing project ":p)
improved engine (more fps
) -> just compare the difference of performance between q3 and wsw. Q3 allows a lot more FPS, I know that there is no cell-shading in q3 but I suppose it can be improved 
news gibs -> sry for saying that but imo the gibs are horrible atm
, and there are some missing textures on them 
new electrobolt & shaft model
-> I think the lasergun model is too big and the electrobolt one is ugly
(imo). However, I really like the shotgun 
new electrobolt styles, same thing for the lasergun and more... xD -> as some people said before, only one sort of shaft/rail is quite boring, would be cool if we had more choices
(something like CPMA/Q4MAX)
Oh and I forget new sounds 
Yes, this ISN'T as important as that but imo it can bring the game more enjoyable
