Along the way, we’ve taken a close look at items that provide the biggest power gains, many of which were introduced in 1.10 as part of a sweeping dungeon itemization pass. That patch was when Tier 0.5 gear was introduced, and Relics were added to the drop tables of many bosses. It also adjusted drop rates and drop locations of a lot of gear (to make room for the Relics). We’ve gone back and reconstructed many of the most heavily affected drop tables as they existed prior to the 1.10 patch, and we’re planning to update the drop tables alongside the Ahn’Qiraj War Effort. Prior to the Ahn’Qiraj unlock, most of the drop rates and locations will look as they did in the patches prior to 1.10, with exceptions—there are lots of little changes made in earlier patches that don’t have a big effect on player power, and in those cases, we’re planning to use the 1.12 drop rates and locations.
In the third phase, we’ll introduce the first Battlegrounds: Alterac Valley (version 1.12) and Warsong Gulch, alongside with their associated vendors. One thing to note is that there were a couple of updates to these vendors over the course of the original patch releases, so some items won’t be available right away. For example, the Spell Penetration trinkets available from the Warsong Gulch vendor weren’t introduced until Patch 1.9, so we’re currently thinking that we’ll add these in phase 5.
