I used to raid. I found it rewarding for a while. However, it is just a treadmill.

New expansion. Repeat above.

I found I enjoyed the game a lot more when I did a lot of things OTHER than savage raids. Sure, I do my 24-man raids since they can be fun. I run expert sometimes, but frankly - since I'm not raiding, I don't need to be on that treadmill anymore. I found other enjoyment in this game that (to me) is far more rewarding. But my hat is off to those high skilled players that clear savage in the first few weeks.
