I miss that evil character! She shows up at Gilneas when she conquer Gilneas and at Silverpine Forest for the Horde questline with both was epic.
Now we don`t know nothing about her. At 5.3 patch or at last 5.4 patch she should show her action again!
Maybe she fights against Garrosh Hellscream at the last MoP raid ?? That will be awesome, or what you guys think??
