Players level 10-60 who haven’t logged in for 60 days will receive an optional “Welcome Back Gift” in Patch 10.1.5 consisting of gear, bags, and the option to clean up the quest log and teleport to the main city.
Characters eligible for the Welcome Back Gift will see a Gear Update Button in the left corner of the screen.
The Welcome Back Gift consists of item level 174 gear for Level 60 characters and 4×22 slot bags.
In addition to gear for your current specialization, you will receive a bag with weapons for your off-specs.
The quest log clear is optional and you will see a pop up before entering the game. In previous PTR builds, your quest log would automatically get cleared. I would personally prefer to be able to browse and pick the quests I want to keep in the quest log, though.
