Servers should automatically rotate maps every round or so. It gets boring to play the same map over and over again, and it's an inconvenience, especially if you have a slow computer, to have to leave the server and join a different one for a different map.
Implement an optional autosave feature, that would autosave after every round if you have it checked. Please! I was almost done with my entire track one time through and my computer froze up for some reason, and closed my explorer page! I know I probably should have saved, but still, autosave's a good idea for morons like me! (plus if you want developers to see)
You're losing a fairly noticeable amount of your player base because of ridiculous things that should never happen, such as the stupid Unity Player crashes.
The fact that people can SPAWN STARING AT YOU FROM LESS THAN 5 FEET AWAY AND YOU CAN'T HURT THEM annoys me slightly. This doesn't just happen on the edge of the map either, especially on free for all. It will happen in the middle of a firefight -.- FIX THIS PLEASE
An issue that this game needs to fix: The fact that you're wandering around a map, like Red Dawn, and enemies spawn in front of your face... you can't hurt them, just hop around and hope they're a bad aim
The fact that you hit "join game" and then it loads everything THEN disconnects for a full server is annoying.. it should check server capacity first so you don't have to sit through loading.
There needs to be a way to increase the cost that people pay for things.. it makes it a lot more interesting, because that could mess with reviews, and instead of helping you get more money, if you aren't careful you could lose a lot.
