The original passive Mastery bonuses players were to receive according to how they spent points in each tree are being replaced with the automatic passive bonuses earned when a tree specialization is chosen. These passives are flat percentages and we no longer intend for them to scale with the number of talent points spent. The third Mastery bonus which was unique to each tree will now encapsulate the Mastery stat, found on high-level items, and Mastery will be a passive skill learned from class trainers around level 75. In most cases the Mastery stats will be the same as the tree-unique bonuses we announced earlier this year. These stats can be improved solely by stacking Mastery Rating found on high-level items.
