Leveling my first priest and I've come to realize that Shadow spec have no procs to watch out for and must be talented, namely FDCL and Divine Insight. If memory serves, every other spec in the game has atleast one thing to keep an eye out on (Arms and Sudden Death, Surv and LnL, Frost DK and their horrible proc-based play, etc). Having a blast right now with my tentacled buddy Mindbender as he rapes 5-6 targets dotted up while glued to the floor with Void Tendrils. I'd hate to give him up for the supposedly superior single-target Insanity or the recently nerfed Mind Spike procs; would've been nice if FDCL was baseline.
Definitely choosing Divine Insight over Power Infusion, as I like the idea of Shadow not being super reliant on burst cooldowns, and insta-cast MB seem too good to pass up. I just hate the idea of having to choose between the two. Twist of Fate seems great for leveling and battleground, but again I have to to give up on a proc. Leveling w/out something to watch out for other than a 3-Orb DP gets... mundane after awhile.
TLDR- Not having any baseline proc kind of blows, for me atleast. Do you guys think its fine/bad talent design?
