Well, Jaina has the "power of the thunder king" (How powerful was the thunder king lorewise?) in a staff, so depending on how powerful the thunder king really was and how much of his power is in that staff, that could count as an "i win"-button.
Where IMO the lore bias lies is that when Garrosh has an "i win"-trick (And he had several, most of "Wolfheart" is graphic descriptions of night elves dying in droves to his bag of tricks), he uses them, the whole freaking lot of them, but when the alliance has an advantage in any form it either gets ignored (Does Jaina do anything with her thunder-king-stick at all?) or the alliance does the lawful stupid thing and decides not to use it, that's both illogical and grotesquely biased.
