Honestly, I agree with that as a Mix player, But Race server is just all about racing, While mix you got RTF, NTS, CTF, SH and DD. All of them require luck and skills, As i see, SH and DD are the most two modes that require skills, Shooting in air, How to get someone from running in DD, trying to figure out how to beat it, See? It's simple.
So Let's talk about NTS. It's right all about luck but, Some maps need skills in cornering, Just try to play all those modes once and say your opinion later
