Yeah, I guess I didn't see where changing stat priorities really added anything to the spec or made things more interesting. Mastery could be stronger depending on how important your burst window is to accomplishing some sort of goal, but for sustained damage it remains unchanged.
I don't like how long this has taken, but the talent changes are so much more even now than previously. I remember at the start of MoP INC+3min Vigil was the only choice b/c it outshined the others by such a large margin. SotF imo remains the only outlier now. Perhaps it will be redesigned(hopefully) or the proc chance buffed. Even this tier was pretty much Inc+vigil or inc+hotw. I just prefer more choices and changing things around a bit to keep it fresh.
Also something people are forgetting I think is that the talent system isn't supposed to force you into one talent because it's better. You should theoretically be able to play with the talents you prefer in most situations. I guess maybe if a group of adds weren't dying fast enough you might be "forced" into speccing DoC for more cleave damage, but seems like a thing that would be limited to heroic raiding. Generally, talents are a personal preference.
