you're right.
only Archimonde and Sargeras can take her down.
Kil'jaeden, Titans, Elune, Malorne, Guardians of Tirisfal, Deathwing, Aspects are all weaker then her by a mile.
its not about how they got their power (heck, Azshara got the Well). its about who is above who and pre skip Azshara definitely isn't above the Guardians of Tirisfal.What? Guardian of Trisfal is only that strong because he is empowered by the council. Medivh is that powerful only because Aegwynn refused to return power that council infused her with and poured everything in Medivh.
