Some of the frustrations I have.
Jumps Jumps Jumps every single time. Pretty annoying map to be honest. Tired of how everyone keeps voting to replay that race every time.
Another one: When everyone leaves a TDM and I am the only person left on the team. Another one is how for some reason, this guy manages to take me down and I unload a whole clip of AK 47 rounds and he isn't even affected.
One of the other ones is how you can use guns from your character that was in free roam. Yep, buy a whole ton of ammo and customize it and have a much higher advantage over everyone else who may not have as much cash to get powerful guns.
