together with the new demon life forms we will be seeing, i predict:
all of the major lore characters we know will be involved in the initial confrontation with the new legion invasion. During it, a new form of demons will
take control of these champions/imprison them, leaving their weapons behind, for us to take and use in freeing them from legion influence.
These characters will then be featured as major strategic goals in upcoming raid/dungeon fights.
Better than just letting them die
