so i tried the 48/13 heavy disc build in arena (2v2,3v3,5v5) and in bg's. The turn out is pretty good. In 2v2 and 3v3 my survival is really good and im able to keep the tank up for a long enough time (and most of the time i didnt die). Pain suppression is an excellent choice for me for when i get 2 dps on me, i pop that, bubble, gheal,renew,and pom, and its like they never touched me. 5v5 is a different story, i get like 4 guys on me and die within a few minutes. But for an undergeared priest trying to survive in arena, this is a pretty decent build.
i did change 1 thing though, instead of enlightenment for the +5% everything, i did the 2/2 imp fort, and 2/3 imp shield, i saw a great improvement there.
If anyone has anymore critics i would love to hear them!
