I am leveling a priest atm and i wanted to go holy with divine spirit, i was just wondering at what level should i go into the disc. tree or should i go there first???


Please and thank you =]

IMO, while you're leveling, you shouldn't be doing so with an end-game healing spec simply because it's such a PITA to kill anything.  That said, IDS is still something that a decent disc leveling build would have.  Either way, I would definitely start with the points in Discipline mostly for things like Wand Specialization, Imp Fort, Imp Shield, Meditation, etc.  I would probably try to keep Holy not too far behind Disc simply because you'll also want Divine Fury, Searing Light, Spiritual Guidance, etc.
