It'd be interesting if they tried to incorporate Frostwolves into Arathi war front. Sylvanas getting pissed because Drek'thar again refuses to lend frostwolves' aid when stakes are much higher this time around could be something to work with. All in all, there's definitely a lot of drama material there.
Also, more importantly, going after the blind guy in a wheelchair is much more evil than what she's done. Oh you forgetful writers you!
