Also, it is possible that thrall has lost his warrior-like abilities due to his inability to practice enough. He is mainly using WOW TBC Gold his shaman talents following the conclusion of the war using archimonde. Maybe thrall has lost his ability as a warrior after this point. Since he's now holding dragora it's more of a warrior and in the present thrall could possibly take out makgora's day garrosh with an axe throw "for Azeroth!" Like He did to Helya!
I mean even tho Thrall killed Garrosh with his shamanistic powers he was still feeling guilty about how he handled it all and cheap WOW Classic TBC Gold how Garrosh turned out due to the actions of Thrall, which led to him losing his powers.
