How do you feel about suggesting to the administration that they add Zul'Gurub sooner rather than later?
It seems to me that such a solution would liven up the in-game experience for many players.
This won't cause an imbalance in gear levels. The items that drop in Zul'Gurub have a lower item level than those from Karazhan 10.
I can't speak for everyone, but I've already geared up two characters—a Rogue and a Druid (covering two specs: tank and DPS). Just a couple of items left, and both characters will be BiS.
I started playing on Octo a little over a month ago.
All in all, this creates the feeling that there isn't enough content
