Matthew Rossi at WoW Insider wrote this amazing piece on how he felt as a player and how his character felt while doing the Operation: Shieldwall Purge of Dalaran.
These points been argued back and forth on these forums since 5.1 was datamined, and he's hit it on the head.He brings up amazing points, points that havAs a player, especially one who has played the Horde side of all this, I see how this was provoked. I grasp that Jaina went to the mat again and again for neutrality, that she wanted peace, that even after Theramore was destroyed she respected the Sunreaver presence and tried to keep Dalaran neutral only to see supposedly loyal members of the Kirin Tor work hand in glove with Garrosh Hellscream to steal another magical artifact. And considering what happened the last time Garrosh Hellscream got his hands on a magical artifact, I don't blame Jaina for being angry. She's already seen Theramore blown up, she's not going to wait for Hellscream to blow up Dalaran with the Divine Bell. It makes sense.
But I still look at those terrified Sunreavers running helpless in the streets of Dalaran, and an implacable force simply teleporting them to be imprisoned. I still look at myself, swords in hand, hacking down any armed resistance and even invading shops to kill the proprietors. This war with the Horde has the very real danger of making the Alliance more like what it fights, and today I did quests that very much felt like those giving the quests had slipped over that line. But let us not pretend that I didn't very much enjoy the turnabout while I was engaged in it.
