Karazhan is the greatest five man dungeon Blizzard has ever created.

I just got out of a ridiculously epic marathon run of the new Karazhan, and I want to say that it's probably the most fun I've had in a long time in this game.The bosses are very challenging, often to the point of wiping the group if you fail a particular mechanic, and they are long enough to feel like you accomplished something once you finally kill it(it brought me back to the time of screaming in vent when we killed 40 man bosses).Blizzard has created a dungeon with just the right amount of balance between needing tactics and coordination and making a dungeon seem unbeatable by non guild groups, and it feels amazing. If Blizzard can continue to produce content of this caliber throughout Legion, I am confident in saying that this will be just as good or better than Wrath of the Lich King.Now with all that praise out of the way, I do have two complaints, one minor and one major. First of all, the run back if you die to Moroes is just way too long. And lastly, at least in my opinion, Curator and Mana Devourer unfairly punish groups that are melee heavy. The amount of damage that goes around during Curator is absolutely insane with a melee heavy group, and running around to gather loose mana during Mana Devourer is a challenge to say the least.Anyway, thanks to Blizz for some good fun. You reminded me why I don't mind giving you $15/month.P.S. It's good to have Icebound Fortitude back.
