So there I was last night, bored and headed to Blackburrow, I was pulling (level 26 bard) mobs up top and casting Mez on them to allow players to kill them, the solo players started a party and I kept pulling them, then I drop and when I try to log back in....
Your account has been suspended?
No GM came and told me to stop, let alone did I think I was doing anything wrong? I've heard of players getting paid (PP) to do this for players, I myself have been in the Warrens where high level players pull almost the entire zone for faction gains.
I'm confused as to why this happened and as to why I was not given a reason?
I have left a petition but there is no response.
