Thrall's journey to badassery and overpowerness it is not much different by other characters, to be honest many of those have even less details (Jaina being the most power mage on Azeroth just because she was talented and like studying, overpowered warriors like Saurfang that are what they are because they are old and veteran badasses that saw any kind of shit in war ecc.); considering how much Cataclysm was blatantly tied with the elements fucked by Deathwing and messed by the Elemental Lords, Thrall, considering his huge development as powerful shaman and important lore character, made a lot of sense as "hero" of the expansion. Nothing else to say about it, really.
