The new PTR 3.3 build released yesterday, introduced a new high-resolution model of Jaina Proudmoore which makes stand above all female human models as unique. Blizzard plans to overhaul other leaders when it makes sense to do so in future content patches. The new model may be found in Theramore and in the Icecrown Citadel: Forge of Souls dungeon.
The new model looks pretty nice, in comparison to the old model which can be seen still in the Icecrown Citadel: Pit of Saron dungeon. King Varian and Lady Sylvanas Windrunner had similar overhauls during the Battle for the Undercity event. Who among other leaders do you think deserves a new model?
Vaneras: This is most certainly something we would like to do as well, but art development is something that is rather restricted by time. Our artists are a busy bunch of people, and unfortunately there is not enough time to do everything we want all at once. Right now our artists are working on a lot of different things related to the future of World of Warcraft, things I am sure you will learn more about sooner or later
In regards to Jaina
