This latest update brings our first interactions with the Woses (Pukel-men), Books 5 and 6 of the Epic storyline, 2 new regions, 3 new instances, an increase in the level cap to 105, and some behind the scenes changes to Avoidance, Mastery, and Mitigation. There is also continuing work on the lags/disconnects, especially in PvMP areas. I think my favorite change is the addition of Task Boards to the Housing Neighborhoods. These provide access to every task, with 8 boards broken out by levels.
