Hello everyone! I am a resto druid in a somewhat casual raid group. We started raiding pretty recently and have cleared normal ToT with a healing comp of myself , and a holy paladin with our shadow priest speccing to disc to act as a third healer when it was needed.
Unfortunately , our holy paladin had to quit raiding due to personal reasons , we have been working hard on recruiting another healer , but we had no luck finding a good holy paladin. Due to how long it took , we decided to finally take a disc priest for a spin. This should not be a problem for the normal modes , as me and him should be able to two heal everything easily. But we intend to start delving into heroics , where I know some fights will require 3 healers. At that point we would have no choice but to have 2 disc priests and myself a resto druid as the healing comp.
I'm not well versed in Disc Priest mechanics, so that's why i'm not so sure about this. Is it possible that having an additional disc will nullify the effectiveness of the other?
