SotP & GC are roughly the same DPS per talent point, single target...

SotP, returns more damage per talent point then GC, on any rotation, except AOE.


SotP Does not require a GCD to do it's talent damage.
GC Requires an RNG Proc, at an optimal time, followed by an optimal opportunity (i.e. filler location in rotation) in order to do it's DPS

In my book, SotP is superior except for:
1) AoE rotations
2) Arguably an extra interrupt occasionally.
