A number of guilds have graduated from Karazhan in the last month or so, but instead of moving into 25-man content, the majority are turning to our new favorite troll town. Of course some of them are dabbling in Gruul's Lair but I dare say Lady Vashj isn't getting as much company as she used to.
There is definitely something to be said about the fact that ZA is 10-man content. If you have a great Kara guild but not enough numbers to move up, ZA is a blessing to say the least. But is that a good thing? Ultimately, if you want to see Black Temple, you're running out of time, and postponing 25-man content is not helping your cause. The expansion will arrive sooner or later and when it does, people will not be interested in killing Illidan anymore. They'll want to see Northrend. If you've tried to put together a Naxx run lately, you know what I'm talking about.
So what do you think? Is ZA helping people get the gear they need to succeed? Or is it keeping them away from the prize?
