WOW - Possible Changes to the Priest's Discipline Tree : World of Warcraft General Discussions

Eyonix teased priests with this short statement about the Priest's discipline talent tree.

Though some priests have found a use for the discipline tree, right now, it doesn't quite have a solid purpose/goal, but rather seems to act as a supporting tree. This is something we plan on addressing with Wrath of the Lich King. Originally, the goal of the tree was primarily intended to provide staying power, vs. the holy tree which provides throughput.

Also, so you're aware, the 41-point discipline talent, pain suppression, is being changed to be usable on others for patch 2.3.
