Why are some players so utterly s*** scared of advancing ?

iScending: I feel your pain! I don't play arty often so whilst I'm not in your predicament I do tend to get annoyed when your entire team lines up as a firing squad and just wait. And wait. And wait. "n00b light scout!" *light tanks takes off and gets blown up as all eyes were on him* "n00b light l2 avoid shells!" ""   Usually I can't stand this and regardless of what tank I drive I do my utmost to spot as many ppl as I can even if it will lead to my demise.
