Coming back, looking for some adviceFollow

Hello all.

I've finally been convinced to re-up for WoD after taking a nearly year-long break. I've been pouring through the reams of information on the expansion and the wrap-up of MoP, but I still have a couple questions on which I'm looking to the community for some advice:

1. Is there anything in particular I should do with my current toons so that I don't miss out on something which is coming to a close with the new patch? I never did much PVP or end-game raiding, but is there something I should do to not miss out on a mount/achieve/other cool experience?

2. I have a 90 DK, mage, hunter, monk, druid, and pally. I'm thinking of using my 90 boost for either a priest or a warlock. I've previously played both to 30 (and the priest to 80), but that was back in WotLK days. For you clothies out there, which is more fun to play currently? I appreciate the ability to dual-spec healing and damage on the priest, but the lock appeals to my evil alter ego. I'm sure I'll enjoy both, but I'm having a hard time reading between the lines on all the updates and appreciate your advice.

Thanks, all - looking forward to getting back into the community.

Cheers,
Jorge

Ahh, good deal. Thanks for the feedback. I'll have a look and see what I want to get done before the patch hits.

Thanks again,
Jorge
