Thank you, you're a perfect example of the kind of person that's not a PvPer, maybe a PvP grinder, but not a PvPer.
Also, I can go to Alderaan, Tatooine, and Hoth and find Imperials instantly.
Who wants to kill lowbies you say? I'm a griefer you say?
You might not understand how social structures work. But generally, if a lowbie at this point gets killed by a 50, they either hop on their alt, call their guild, call in general/PvP chat, or all of the above. Next thing you know you have a massive group coming your way. This builds until people stop coming back.
