The reason being their respective WOW TBC Gold childhoods and experiences. Thrall was a child and spent his teenage years training to be a Blackmoore gladiator. Fighting was his life. Following his escape, and fought against Durnholde that was comprised of numerous battles and raids against the forces of Lordaeron. As a side note, the "Lord of the Clans" was not shy about how much taller Thrall was as compared to regular orcs. The third war followed his victory, and was the war that decided the fate of the entire world. In the end, he took his people to victory along with the night elves as well as humans. In a much shorter time-lapse Daelin takes over Durotar and forces Thrall to bring his people into battle yet again. My point is that Thrall was a fighter and trained throughout his whole life. Although there were instances when the tyrant wasn't fond of vanilla WoW, or Durotar's creation There were also some lapses during his career. His life was filled with fighting more buy WOW Classic TBC Gold than anything.
