Its even worse on PVE, if you are flagged for any reason you can bet your behind that your gonna have somebody go for you. Not to mention they'll milk it for all its worth since they may not get another chance outside of a BG. Take me for instance, after helping somebody out in ZF i forgot to unflag myself(the stairs) - winterspring and i get double teamed by two shammies. I dont even bother corpse running and rez at the GY. On the bright side found same shammies down trying to take out the elite giants so i jump off the bridge(parachute), mount up and aggro another giant, dismount near the horde and proceed to bubble up and get them slaughtered, after that i just kill them both after they rez and go my way. Do i hate all the horde and call them all names or demean them all just because i'm slightly miffed? Heck no, but a bit of vengeance does help lift my spirits now and then :)
Also how can you be in a "CONTESTED" area if its PVE and you did not mention why you were flagged? I dont take heed of the "it was my brother business".
