I used to always use SoR to tanking (after applying JoCr or JoW) but recently switched to SoV for most mobs that take a while to go down and all bosses. I like the constant threat trickle SoV gives me once 5 stacks are up but its really annoying the times I watch the timer tick down from 15 seconds to zero and watch all those stacks slide off the boss. It happens alot more than I'd like tbh.
I haven't noticed that much difference in aggro generation between the two (although SoV is better when offtanking and trying to keep threat up with the MT), so was thinking of going back to SoR and maybe picking up the libram and the Imp SoR talents to see if it boosts my threat significantly.
Anyone any thoughts or maths on this for me? :)
