I was interested to find out via our very own Mike Schramm the Fleshcrafter that Blizzard has a YouTube channel now. The main reason I was interested? Because I can watch the Wrathgate cinematic several times a day and not get tired of it. It's simply one of the things I enjoyed most about Wrath of the Lich King, a potent, powerful and personally experienced series of soloable quests that leads to an awesome rampage through Undercity that creates more tension and drama than it solves. No matter what toon, I've made sure to go through this complete quest chain as soon as I can, as both Horde and Alliance get to see some fantastic lore goodness and interact as near equals with the big figures of their respective factions.
Who gets to escort Jaina to her meeting with Thrall? You do. Think of it this way: remember in WCIII when Rexxar and Thrall met up with Jaina? This time, it was you and Thrall. It really did an amazing job of injecting immediate, powerful connection between your character and the great figures of the factions, as well as bringing the war against the Lich King (and the presence of other forces seeking to take advantage of it, ala Putress and Varimathras) back home to the cities of old Azeroth. Who can forget seeing Orgrimmar crowded with refugees?
Moreover, watching the Alliance soldiers rally around Bolvar and the Horde come sweeping in under Saurfang the Younger always gives me a bit of a nostalgic feeling. This was the culmination of the 'This threat's so big we have to work together' mindset that saw us form the Might of Kalimdor under Saurfang, that united us against Kil'Jaeden at the Sunwell. This was the last, best hope for peace and unity. Had Bolvar and Saurfang not fallen, had the Forsaken not been split by civil war, if a unified front persisted against Arthas at this critical moment who knows? We might well be looking at the first steps of real detente between the factions, perhaps even a pan-Azerothian league of states and powers that includes all of the Horde and Alliance races as Putress strangles it aborning.
