Whether it will be fun to play or not - will depend on server hosts. This feature is more about giving modders more room to make new game modes and scripts rather than trying to use this gravity setting on non-scripted server with default game modes and maps.
It would be so awesome if you could jet in any direction you want (i mean jetting without the use of movement keys). With this and zero gravity setting Soldat would easily become just like Crimson Glory ;/
Ever heard about supply and demand? If there would be a need for more normal servers, people would simply create them. I never had a problem with finding normal CTF server to play on.
A quick look at http://rr.soldat.pl/ and what we see:
Number of normal servers = 457
Number of WM servers = 56 (10-11% of all)
So stop with this anti-weapons.txt bullsh!t already.
Those don't include servers with bots, do they?
Also, i don't know how you manage to find normal CTF servers, but I personally don't find too many of them either. Most of them are those !elite snipe&slice, climbing, hexers, MMODs, anything but normal CTF.
