Like, if we only show the MC the parts where Thrall stops Archimond, Thrall frees their people, Thrall attacks Deathwing, Thrall helps the trolls, and Thrall saves the tauren... then yes, we could have someone who sympathizes one orc. But those are exceptions, no? You can't expect the MC to care about Blackhand as he literally depopulates a fifth of the continent, can you? Or Garrosh? Or Sylvanas?
I mean, burning down a tree with the trunk as thick as an island isn't a one-man-job, yeah?
