I would love to complete the invasion event one of these days....
I don’t know if it changed, but I did the event like a month ago. Sometimes it fails if the zerg moves too much from the NPC’s. Like the zerg tends to dive into the enemies coming from the front, while there’s often groups coming from the back as well, striking the largely undefended NPC’s. Keep the zerg closer to the group, and have some heals going.
Just who the hell do you think I am!?
