On the one hand, the Thrall story in SL was boring, derivative of Warlords in framing his relationship with his mum and being tortured by hellrobots to regain his connection to the elements in a realm where there aren't any was dumb. On the other hand, mere words can't describe how little of a fuck I give about retreading this yet again when the only time to do it right, that is in SL, where he failed to meet Garrosh who's at the heart of him losing his power, was missed. It's blindingly apparent they've no idea what to do with him and he was only put on the marketing materials for a token Horde presence and because he represents Metzen. Even his role of being Anduin's therapist can be, and in fact is, fulfilled by literally everyone else in the plot who isn't evil.
