Satele isn't close to Malgus, though. Satele was disarmed, and Satele only "won" because the other dude distracted Malgus.
And Malgus has probably a better growth rate as well, considering how much he grew after he killed his lover. And slayne also convinced me that Malgus >> HoT, but I can't copy his argument rn.
Anyway, is it now officially confirmed that Malgus is dead?
