that mean gonna be hard to find place on raid but on Party 5/5
Yes that's pretty much what it means. On top of that, since Shadowpriests in vanilla do already have issues to carry their own weight, Guilds will usually only fill that one shadowpriest spot with the best and most comitted shadowpriest they can get their hands on. If you have any questions regarding both Shadowpriest or Holypriest feel free to contact me ingame (Alliance side)
