Is Karazhan really as fun as people say?
Yes, it is. Karazhan is a nice instances with loads of different encounters. It pretty much requiers everyone to be awake at all time. The mobs hit hard, the bosses are fun but the loot isnt that great.

Its only a matter of time when we need to send multiple groups into this Dungeon.

Some discussion has been around if The Armory is a good or bad thing. Personally I think it is a good thing.

Atleast it is useful for checking gear and specs of players that apply to your guild. Some think its invastion of your privacy and really disagree on showing your characters information public.
Good or bad, Blizzard still has alot of work to get it working properly.
