I don't play Horde and don't know too much about lore but I've kept up with a lot of the beta updates and previews. From what I've seen, in the troll starting area you see a type of cut scene that basically shows how much the leader of the trolls hates Hellscream. He even states that one day he will kill him. Sylvanas seems to also be hated by Hellscream in the quest that let's us know why Val'kyr are now being used by the horde. He hates the fact that she can now raise undead under her control and even compares her to the Lich King. The Tauren on the other hand seems to me to be a lot like the Night Elves. A more peaceful race that would rather avoid confrontation unless it directly impacts the survival of the Tauren. Something that is very unlike Hellscream.
So my question is, with the way Hellscream is and the seemingly growing hatred for him by the other faction leaders does anyone else think that the horde might plan an "undercover hit" on Hellscream somewhere in this expansion?
