First of all i apologize if this has been said before so feel free to lock this thread and point me in the right direction.
Over the last few weeks after going from a shadow priest to a disc priest for the guild purposes i noticed all disc priests stacked mastery for absorbs what makes perfect sense in a 25 man guild. While browsing this forums and many other priest forums i notice the odd post about crit is better than mastery for 10 man healing, so i thought i would search the internet for a better answer but i wasn't about to find enough information to warrant a respec from mastery.
Ive searched for some of the best guild in the world to see how they spec their priests and yet again its totally different from what ive read and been told, also im not willing to just copy these top guilds priests without having a decent understanding.
So i was hoping some of the priest community of this forums might be able to enlighten me.
