Funny, my 70 ret can take out an enhancement despite the wolves, but resto seems like it can heal thru everything.
Divine Storm during wolves. I'll WoG early so it's off CD later if I need it. I often use Repentence to close distance. And hammer away. Get him to 30%, HoJ, 2-3 exos, Templar's if it's at 3 Holy Power, Rebuke if necessary, and a HoW usually will finish him.
Seems like a lot of Shammies don't use their totems to full advantage.
Just dueled a 73 resto and he healed himself thru everything I did, including procs, without going below 80% mana. He used mana spring totem only.
I don't know if people consider ret viable at 70. I like it, but get crushed in duels by mages, rogues, and at least one demo lock who stuns like a rogue. I only beat rogues if I get a couple Art of War procs, and then the win feels cheap. Priests are tough.
