I wonder where do i report people? Im trying to grind in an area and ofc there is another warrior, but he have a druid following him, just casting heal and renew when the warrior needs.. aka multiboxing, and its agenst the rules, i wouldent mind if the other guy walked by himself then i would know its 2 people.. but this is just to obvious.. where to report unfair players like this?

Fill out an ingame ticket. Player harassment (either choice) worked friday for me. GMs are pretty quick to respond.
