WoW 4.3: Patch 4.3.4 Live This Week
We haven't talked about it much, but Patch 4.3.4 will be going live this week with two main changes.
The first change is the addition of BattleTag support in the UI. Unfortunately there does not appear to be any way to add a player by their BattleTag at this time.
In the current state on the PTR, a player can add a friend by their BattleTag in the Diablo III beta, and then interact with that friend on the WoW PTR servers. This means that players may be able to add friends in a similar manner through the Diablo III game once it is released on May 15th, but will be unable to do so until then.
New Support Options
The second change is the addition of additional support options, such as reporting a player for their name or cheating from the target frame, rather than just the friends list or manually filling out their name in a ticket. The GM ticket UI now also allows you to submit bug reports and suggestions in game rather than on the forums.
