Yeah, I hope they make it viable on fights where we don't have to burst anything down, like along the lines of a Spine tendons; I enjoy the random procs too.
In general, though, I really hope they don't make any more changes to shift us into more burst damage; they have been trying to balance Ret PvP around burst for years and years, and it's really just not working very well. I wish they would just try making Ret a heavy sustained damage spec, which exhausts the opponent's healers, over the course of a few minutes, much like a warlock does with constant multi-dotting. We just don't have the tactical tools to be a real burst spec, and at best we end up relying on a Rogue or something similar to actually set up a burst opportunity.
