i once read something on the wow forums about a 4priest 1ret pally combo which i think would work well with boxing. I cant go into as much detail but ill try and give u the gist of it.
Pally must have improved sanc aura, +12% holy dmage.
And have all your priest set to holy/disc specs in where you use smites spamming and maybe 1 misery spec priest using smites.
Have 4 mendings up at the start and have them bounce around the while game /cast [target=self] pom.
Also having 4 holy novas with improved spell dmg i think would be not devistating, but pretty nice melee attack counter.
There are a couple of things like PI and divine fury, Surge of light which in theory would make it a pretty good group spec and something that would be very uncommon and people wouldnt quite know how to counter it.
Thoughts?
