I'll admit it: I liked Arcatraz. I know, I know! It's supposed to be awful, how could I like it!? Well, while I didn 't necessarily like the layout of the dungeon and some of the trash (ethereal room, I'm looking at you), I like how it brought a lot of nostalgia from WoW Classic with it. A few of the trash mobs were pulled straight out of level 60 raids, though toned down a bit, and the last boss was like the "Best of Level 60 Raiding." Flamewakers? Qiraji? Awesome!
This is why I love the upcoming Violet Hold, too. Dalaran's Violet Hold in Wrath of the Lich King is a throwback to everything we've done so far. To the people who have been raiding since the beginning, this dungeon is going to prompt a great big, "Man, do you remember when..." moment. For the people who haven't been raiding since the beginning, this dungeon will show off a lot of fun mechanics they've never seen before.
