I'm really, really hoping we'll see Magni in the scenario. Perhaps he'll intervene at some key moment in the scenario, turning the mountain itself against the Zandalari-backed Frostmane Trolls.
I generally believe he should remain in his current state, but that his powers need to become more visible. So he'd basically become the soul of Khaz Modan (dare I say a god of Khaz Modan?), acting as a sort of guardian spirit of the region. His previous inaction would be explained a combination of being disoriented in his new state and using all his power to keep the Cataclysm from seriously affecting Dun Morogh.
Roleplaying, hardcore Raiding, running LFR on the occasional weekend, PvPing, rolling alts, achievement hunting, pet battling, or just enacting an endless series of whims, I don't care how you play WoW. Just as long as you have fun doing it.
Which is why I don't mind the title at all.
But without having to go off on a major tangent, everything else surrounding it has been rather naff. For something so major to the Alliance it doesn't feel like they're really giving it their all when it comes to making it believable and grand.
If this scenario is a Trial of the High King then I hope it goes well. I hope I'm right in this assumption but currently the Alliance is missing a Scenario on the patch notes (2 Horde, 1 Alliance and 1 neutral scenario are listed) might mean that if this isn't it then the one we haven't heard anything about is probably it.
