I don't see how something that controls BT's crit buff being pushed out of the rotation
isn't objectively an issue, especially during Execute phase where, since it's pushed out almost completely, BT has absolutely no way to have a better chance at critting. If FS was nothing but filler and didn't have TfB (and Frenzy if you talent that), this wouldn't be an issue at all. Simple filler being pushed out for better things is perfectly fine. And for the record, I hate Furious Slash and would love to see it go away or simply become filler. That's completely subjective.
And it's not really subjective at all to say that FS being pushed out devaluing our mastery due to vastly reduced Enrage uptime during Execute phases is also an issue. Enrage, as it stands, will likely have lower uptime due to FS being pushed out. Again, something being pushed out is fine, but one of the core mechanics of our spec and its mastery being reduced drastically in only 20% of a fight is 100% objectively an issue. We
need consistent ways to become Enraged in ALL phases of a fight, and as it stands currently, FS doesn't do that. That's objectively an issue, and it's something that has been an almost unanimous piece of feedback for all of beta and certainly a good deal of alpha.
It would be nice if more was tied to BT itself, like its crit chance and probably Odyn's Champion since sub 20%, you really don't have any way to proc that minus talenting Massacre, but that's me.
But objectively? Yeah, FS is an issue. There's nothing subjective about that.
As I get farther and farther into math (woo woo advanced analysis and linear this fall), I forget simple things. If there aren't letters in my math, I don't remember how to do any of it.
