That's because you seem to stop at being a victim, instead of getting it together and kicking their ass later, alone or in group.
Wich come to think of it is hard to do if they fly of after the kill, ironicly.
I do have understanding for the low levels tho, the killer is usually long gone by the time your main's on the spot, if you've not gotten your main there before you got killed.
They did seek out people who like pvp, they rolled on a pvp server for it, so anyone who does not, well, wrong server, again.
