Have you even READ the things I post in here? I've repeatedly suggested making the Pistols and Military Sniper fire actual projectiles instead of that hitscan bullstuff.
Use the Gun and Guns Akimbo instead of the Pistol/Dual Pistols. The Gun does more damage but fires slower, and fires a normal projectile.
If we fight with the same weapons at a good 250 distance, I should kick their ass because I know how to aim and fire properly
250 units (500 bricks!) is
not a good distance. The fastest "normal" projectile takes two seconds to get there so can be dodged. Hitscan guns will be the only reliable things to hit with. Build a smaller arena.
If you don't like what's happening,
make your own server with whatever balance you like. If others agree that it's better then they'll stay there.
Personally, I think that a decently made small map is much preferable to point-and-click sniper wars across mountains, but even that is better than a neverending stalemate where nobody can hit the other with slow projectiles unless you spend five minutes walking. If anyone gets there it's still pointless as the attacker has one life and the defending team has infinite fast respawns.
