Tides Of War
A couple of years ago, I wrote about Jaina Proudmoore’s progress as a character after the loss of Theramore and the events in Mists of Pandaria.
Baine Bloodhoof certainly wasn't a high-profile leader in Warlords of Draenor, nor was he more than a minor character in the events presented in Mists.
Sylvanas Windrunner had a choice to make at the end of Wrath of the Lich King, and initially, she chose oblivion.
Although she's not necessarily heavily involved with Draenor, Jaina Proudmoore, leader of the Kirin Tor, has made her presence known. And her current behavior is slightly confusing to those that have read the novel War Crimes, but not necessarily out of character.
