Maybe I've missed something obvious, but I can't seem to understand why we're suddenly fighting the Alliance after Deathwhisper, enough so to gun down their ship (or vice-versa). It's not that fighting the Alliance is an irregular thing, but Saurfang holds the quote "Perhaps this could quell the unrest between the Alliance and Horde," and ten minutes later, he's captain of the S.S. Dwarffucker.
Does the Alliance dialogue have something of importance that the Horde doesn't? Because from our side, we go up the elevator, and suddenly it's common knowledge that we're supposed to be sparring each other while Arthas sips tea. Hell, even from that moment, they mention Saurfang waiting for us to assault the Alliance gunship. Also: Where's Fordragon and why doesn't he lecture us again, like in ToC?
So, something secret and invisible happens between Saurfang and the Alliance between the start of the instance, and two bosses later. This fight seems very, very out of place, even rushed. Come to think of it, Saurfang Jr's appearance also seemed out of place and rushed. Not to bitch about rushed content, but this fight in particular irks me every week.
