I don’t know how it is on other servers, but on SBI zerg trains are running in circles day and night farming the champs.
So I’m wandering around doing stuff for my dailies and head into the troll cave to do the grub event. I finish that and see the troll runestone has spawned. I start the event and nearby players help kill the troll. Then the zerg train comes in and starts calling me kitten names for inconveniencing them and that I should be telling them whenever I start a champ event. I tell them that they are inconveniencing me and whoever else is around the area for having to wait for them and they say that there’s more of them and that they are leveling up the fastest way so I should be listening to them. Now I don’t usually care about what other players do to level or farm gold until they started harassing me with whispers.
