After being camped outside of Darkshire for 15+ minutes by a ?? Druid I decided to fire up my Horde alt and have a little chat. (Why not?) His response was "man up and rez you p*ssy."
Me man up? Says the guy one-shotting lowbies because he probably sucks against anyone near his level. I actually logged onto another character for about 10 minutes or so and sold some things in Stormwind. When I came back he was STILL hovering over my body. At that point I just had to laugh.
So after I load my character up on deathwing and working on quests in Thrallmar (Yes I know the hub for high levels to gank low levels) I was killed by 2 level 80s who had around 20-22k hp (my 80 blood dk could kill them but that is beside the point). Shortly after in Thrallmar a level 71 Warlock attacked my Level 61 Warlock. I manage to fear them, while my Felguard and the guards around Thrallmar killed them (my Felguard got the killing blow). I go into the inn to level my tailoring (something I really needed) and the warlock attacked me again. And I managed to kill them with ease.
So moral of the story, don't go ganking in Thrallmar/Honor Hold if you can't handle a level 61 killing you over and over.
