I know mastery SUCK for spriests, so I could reforge a chunk of it from Sorrowsong into haste... Also, if I buy then Stump of Time, I would replace the Anhuur's Hymnal (http://www.wowhead.com/item=56407), I guess?
halp
p.s. Maybe the Sorrowsong trinket is best against bosses?
Personally I stopped using Sarrowsong in favor of Anhuur's and Gale of Shadows http://us.battle.net/wow/en/item/561...=dropCreatures because Sarrowsong is situationally useful while the other two are often/always useful. Anhuur's proc rate is almost on the ridiculous side because often come up multiple times during a boss fight. So I definitely wouldn't switch out that one. Also with Anhuur's since I have a ton of hit I reforged some of that one to 114 haste which is nice.
I would say replace Sarrowsong with the Stump if those are your choices.
Ok but... I'm NOT wearing Sorrowsong, so there's no "replacing" yet. Since Anhuur's Hymnal is a hit trinket, shouldn't I replace it with Stump of Time? Which means I would keep using Witching Hourglass?
I like Sarrowsong a lot as well, like I said above the reason I use Anhuur's and Gale of shadows instead is because once Gale's effect is up it is always up (so basically you have +340sp shortly after combat starts for the whole fight) and the proc rate on Anhuur's is really good and happen throughout combat. Whereas Sarrowsong's can only happen =< 35% and it has a 10 sec cd before it can proc again, so it's effects are severely limited
Witching Hourglass would be nice as well... but I think I have accepted it's not going to drop for me... maybe..
