I really enjoyed playing Disc this expansion, especially since there are many different ways to play a disc priest.
My Disc priest was my Alt, while my Holy Pally was my main... Ever since they changed the way of Holy Pally healing, i've sort of stopped playing it.
Now i've noticed in Heroic 25 man dragon soul, the Holy Priests are significantly out healing the disc priests. Mostly due to the fact that can Divine Hymn every 3 minutes (and being Holy it's healing is increased). I switched back to holy and actually liked it better than disc... Have holy priests taken their spot back as being a better healer than Disc priests, or does it really depend on the fight??
