Seriously, you can't even have a proper FPS server. The guns we have can't keep up with a person's aim, in other words if you start shooting in the middle of the screen and turn your aim to the left the bullets are still in the middle or the bullets are catching up to where you turned, the bullets take way too long to reach your aim (on top of that, its even worse if you have high DPI). This is a major problem, I have experienced close range gun fights where I start aiming a tad bit to the side of the actual player and when my aim moves on the player the bullets still aren't on him and then I get killed. Why can't we just have bullets that are incredibly fast or something similar to hit scans so we can make FPS servers that are actually enjoyable and not about luck.
There are also problems with some rocket launchers (have no radius damage at all) but that isnt my main concern.
