You want to take a couple of 60s with you to level to absorb the experience, or if you have kill missions in STV, go to the area with the mobs and die but don’t release, you’ll still get the credit without the exp gains.
I will submit a suggestion and have my friends do the same, I concur I went out of my way to obtain this for TBC in anticipation. I hope they rectify this, it’s not substantial for them so I don’t see why not.
Can I buy your 29 rogue? I know it's not really BiS anymore but to be honest I use to have a 29 rogue like yours and it got deleted so I've been searching for one.
