Thanks for reporting. Yes, it looks like a false positive. However, this is a generic rule that has been in the database for over a year. So I'm thinking something with Zygor guide's was updated and therefore it is now detected by us. We'll see what we can do on our end to avoid further wrongful detection. In the meantime, I recommend adding these detections to your exclusions list. Here's how:
Formerly, when you visited a new zone, you would be very careful, tiptoeing around, cause everything was higher level than you. But as you dinged (leveled up), you would get more powerful relative to the locals. So you would feel more confident and capable. Dinging came to represent more HP, more Mana, better hit ratio, more crits, more talent points. you felt REALLY good when you dinged, like you had accomplished something. Almost tangible. You would think "now I can go back and take that mob/group that ganked me". And then when you had done all the quests, you would move to another zone and do it again. Fun!
