They did open them back up, took a day or so, just had to answer some questions (what I was using them for etc.).

Thanks for the advice by the way! I figured that for healing in all instances but heroics, the shadowpriests would provide more than enough from vampiric embrace and for heoroics, I could respec one of the priests for healing and let him provide most of the healing. At the moment I'm leaning more towards shammies though, since they seem to be more versatile.

Have anyone in here tried 4priest/paly in heroics? (i did search, but no posts seemed to adress the shadowpriest issue specifically)
