Yeah, I recently just started raiding again. Since I've been back, for the past two weeks, we've downed Gruul plenty of times, one shotting him once, and have gone through SSC, also. Karazhan is easily farmed, which is should be. Although Karazhan is a great source for much needed gear, it's not required for progression. You can get similarly good gear from PVP, and Heroics. A lot of guilds on my server are focusing so much on Kara that they've been running it for months. My friends guild died because all they did was run Karazhan, and never tried to progress.
I haven't got any good drops,
still, which sucks, but the good news is we can clear just about all of Karazhan in a single night, and will be doing it tonight. I should get all the cloth priests drops since the other priest has them all already
