Regarding the Medivh-hate; he gets a solid "meh" from me, with an aside of "Dear God, why couldn't you use contraception and avoid siring a mary sue?"*

Terenas was hardly likely to listen to Medivh, perhaps even more so if he'd revealed himself as Medivh; recall that the last the Alliance heard of him, he'd been killed by Khadgar et al, having brought the Horde to Azeroth. As far as I know the fact that he was carrying Sargeras about in his head was not common knowledge, so Terenas would have had no reason to differentiate between "insane, stupidly powerful sorcerer who unleashed ravening barbarians upon us all" and "cryptic, stupidly powerful sorcerer who wants to avoid having the Legion faceroll us all". The point being that Medivh was not exactly considered a trustworthy source of information - and more to the point, he was supposed to be safely dead!

*Said Mary Sue being Me'dan, the half-human(plus Warden of Tirisfal-ness plus Sargeras-ness) quarter-orc quarter-draenei son of Medivh and Garona. He's in the comics, and he's certain to worm his way into the game eventually.
