Contrarily, Garrosh has almost no experience or training to build on. He was raised by himself without any major enemy or conflict to increase his strength. The Bladespire had taken over the northern regions WOW TBC Gold of the Bladespire's tribe of ogres and they retreated to Nagrand. Although he received training however, it is an orc's custom to hunt and fight. This is only an assumption. He doesn't spend any time in TBC fighting against the Legion or Illidan. Wrath is the only instance that you can claim the proper training was received and exposure to fighting the Scourge. This is due to the fact that it was not his full expansion. Saurfang is considered to be a legend, but Garrosh's experience of two years is not enough to substitute for the years of war. He didn't take part in any significant Cataclysm conflict. As with the majority of MoP The only major battle in which he was involved was that of the siege of Ogrimmar.
There was way too much to write this in words. Betwen both of them, Thrall lived the life of a true warrior. He spent cheap WOW Classic TBC Gold most of his time taking his troops to the frontlines while Garrosh was all talk and sent his soldiers to serve at his command.
