What attitude and potential measures should Thrall or his successors have adopted toward the Forsaken and especiallt Sylvanas Windrunner given the shady, underhanded and cruel nature of the Forsaken, as well as their lack of honor and their willingness to use very pragmatic and dirty means and do very odious things that have nothing to envy to the Old Horde ?
What should Thrall have done other than just letting Kor'kron in the Undercity after Putress' betrayal at the Wrathgate and the discovery of the Blight and experiments made by the Forsaken inside the Undercity ? How should Garrosh or Vol'jin have reacted to Sylvanas' use of Val'kyrs and the fact that she used the Blight on Gilneas, Southshore and other locations in Lordaeron ?
How would they have reacted to the Sludge Fields at Hillsbrad Foothills ?
Shouldn't have they tried to find a potential replacement to Sylvanas already ?
