I don't know if a post on this topic has been created, I can't seem to find one, so I figured I'd start the topic.
In each raid involving a major "end of the expansion" villain being killed, there is a character from the Warcraft lore that usually deals the finishing blow, rather than the 10 or 25 unnamed "heroes" that did all the heavy lifting. Ex: Arthas was killed, Tirion breaks Frostmourne and gets credit. Deathwing gets killed, Thrall deals the finishing blow with the Dragon Soul and gets credit.
With Garrosh being confirmed as the "end of the expansion" villian of MoP, who do you think will land the coveted killing blow and why?
Blizzard (I think intentionally) left the possibilities wide open in terms of lore. Garrosh has so many enemies, it could be any one of them that finishes the job.
I personally think that Wrathion will be responsible for orchestrating the events leading up to Garrosh's (possible) death, but Vol'jin will be the one to say something badass before landing the killing blow ("I told'ya so, mon!"). Although all the horde leaders have justifiable grounds for killing Garrosh, I think Vol'jin's personal vendetta with Garrosh runs deeper than the other leaders.
Garrosh's actions not only lead to the continued isolation and quarantine of the Darkspear trolls, he made an assassination attempt on Vol'jin - and almost succeeded.
What are your predictions as to who will land the killing blow on Garrosh and why?
