The thing that annoys me the most in the whole game is being hit by either snipers, or worse still, tubers. Way to go chaps, while the rest of us are fighting you're fagging about in the bushes on the other side of the map.
Does spotting not only work if you've got the recon spot kit or UAV?
I'm definately in the less than average category. My main issue is changing weapons quickly enough. My mouse wheel always seems to go to Med Kit/Ammo Kit/Defib when I try to select gun. The amount of times I've tried to kill someone with a box and failed is unreal.
Whilst I can understand the noob-tube frustration, it's in the same category as Gustav, Granade and Mortar spamming IMO.
