I was told by a few people that I should not be using renew as a disco priest. I guess they are thinking that a PW:S is what I should be using instead. As far as talent points go, getting improved renew is on the first teir of the holy tree, and I chose to get 3 talent points into that, instead of spell warding, so that I could get down to the desparate prayer and inspiration talent points. In my mind the only advantage holy has over disco in using renew is that holy has more SP due to spiritual guidance, and their renew does some healing up front due to empowered renew.
The reason I am worried so much about this is because I was kicked from a random H HOR by a DK tank (unenchanted) for using this spell.
I figured priests are the most versatile healing class and we have a spell for everything. Does that not hold true for disco priests and this spell? Should I spec out of Improved Renew and pick up Spell Warding instead?
