I think that commonly used commands should be shortened to more compact commands, for example,
/lobby could be shortened to /l
/f add could be shortened to /fa or /f a
/ignore add could be shortened to /ignore
etc.
There should a command such as /colorcodes or any other similar phrase which will then show in your chat bar each and every color code and chat format for much easier use!
If you do not know what a chat format code is, refer to this thread.
Although I selected Web as a prefix this is a in-game suggestion, sorry!
I think that spectators should receive a win if their team won, even if they were already eliminated. Why? Because that player could've worked really hard with his team to eliminate the last players or defended their base exceptionally, but right before the end gets eliminated and thus does not receive a win.
Although the first two are all small and not impactful suggestions, its these little gimmicks or tricks that make a server special and unique! I think that something, no matter how small, can make a difference!
