still the forsaken.
Operation W.O.R.G (Worgen Operatives Retake Gilneas)
Regardless of them having their ancestors at one time to keep them in check, the Orcish Social Code has always been flawed. They put so much value on honour and strength, that the moment someone tells them a fellow race is insulting their honour and questioning their strength, be it by fighting back or simply existing (as was the Draenei case), then they all start frothing at the mouth. If the orcs don't change their values after SoO, another Garrosh is eventually going to pop out.
Thrall did try to change their values. But there is only so much you can do in a few years to change the mentality so ingrained into a society. He never restored the spiritual leader role of Elder Shaman.
