Well thats the biggest problem with starting off at the bottom of the food chain
There is no doubt you are going to get constantly blown out of the water in the early games. Your goal is to get in there and score as many hits as possible (even if they dont do squat)
Your other option is to keep with the bigger ships and score some cheap shots on badly damaged ships (and maybe even get the kill)
To be honist though whenever i play i use the premium account so hanging around for 5 mins then getting some shots in gets some great exp
