recently, a new Priest has joined my guild's ranks, and he has also interest in raiding. Currently his spec is Holy (and he's good at it), but he wouldn't mind changing to Discipline. Now, currently we have four healers in the guild: him, a Holy Priest (me), a Holy Paladin and a Restoration Druid. We have four healers for our 10man guild, because there is usually one person who can't show up. However, I show up 95% of the time, for I am the raid leader.
Now, I was wondering, would the raid group benefit more from him if he is Discipline, or if he is Holy? As far as I know, Holy is the more versatile spec, but I am wondering if two Holy Priests is really viable for raids...
Thank you for your time.
