Is there a rule that prevents players from chain killing you for no reason ?
I've been trying to farm my dailies but a druid decided to waste his life flying after me and killing me on repeat for no reason.
I respawn, he finds me and kills me on repeat, since it's in Icecrown it takes me 1200 yards to fly to my body, at one point I consider this harassment.
How long does it take you to understand that if you repeat the same action and always get the same outcome, it's best to change the course of action?
Have you considered the following
Call for backup
Go elsewhere (in-game, other game, step outside, watch a video) for a while.
I don't know why you'd bother being there after you got killed twice already, unless you enjoy it somehow.
It's a part of PvP server. You have means to deal with it.
