Lord of the Rings Online's Wardens are understandably nervous about the big stat changes coming to the class in Update 10. To help clear up any confusion, Turbine's posted a dev diary crunching the numbers and outlining how the change will roll out.
The big change is that the Warden's primary stat will switch from might to agility, and the class' primary form of avoidance will switch from blocking to evading (although the Warden's shield will still provide plenty of the former). As a result, one block-based trait is being reworked to feature evading, and the devs are looking for ways to beef up Wardens' mitigations now that might is no longer a primary stat.
Because the change will impact Wardens who have stocked up on plenty of might gear, Turbine is offering a lengthy grace period to allow the class' players to start switching over to agility gear while keeping both might and agility as primary stats. The grace period is said to last the full length of Update 10 and perhaps longer.
