Tyrande as anything other than shrew incarnate is a Richard Knaack WOTA novel creation.
Tyrande is a female leader created by male writers and she suffers from birth from the "Btch Leader mode that many men seem to feel that is the only way to create a female leader. Her main action as the player character in WC3 was to murder Maiev’s Sentinels to free the Betrayer that Malfurion had sentenced to eternal confinement. (Mal’s less than pleased about this development.)
The fact that she allowed these Wardens to become so distanced from her over time does not speak well of her abilities to keep in touch with those of the Sisterhood that she delegated leadership to other parties. (I mean really over 13,000 years didn’t she have SOME time to look in on them?)
Some players took exception to Varion’s reigning her in at the Temple of the Red Crane as if Tyrande had been struck by deranged author syndrome and made out of character in order for Varion to look good. What they neglect is that Tyrande was simply showing her normal behavior in a crisis situaiton. Behavior just as in character as when she dived into the Maw on top of the Frozen Throne. Her taking on the Night Warrior mantle was nothing more than just an extreme example of behavior that she has been prone to since she was introduced in the RTS.
If you’re upset about how Tyrande is portrayed, keep in mind that this is the way that she’s been running from the start of the franchise.
