The patch also adds two new limited-time events, tasking players with catching fish on Mirage Isle and defeating enemies in Mistmerrow. Defeating enemies with fish is not really a viable path, but you’re welcome to give it a shot. Players can also take part in the public testing of the skill queue system. It’s not a major shot in the arm of content, but some better event scheduling and more events to participate in should be more than enough reason for a little celebration.
