We're discussing Atonement. People aren't using Atonement primarily for its DPS but for AA. The damage contribution is merely a nice bonus.
The log I linked has 19 casts of Solace, 10 casts of Penance and 9 casts of Smite for 38 Evangelism stacks. The Priest used AA 7 times, which means that there were only ~3 additional casts of Atonement not meant for Evangelism/AA (and that can even be explained via simply using Solace beyond 5x Evangelism for mana). What were you saying again?
