I think to maximise Fury performance brings up a lot of issues that maybe the average joe isn't gonna notice. They are just gonna be seeing buttons light up and smashing them for big numbers, which is why I think it will be popular. For more progression/high end players the closer you get to maximising the spec the more holes you're gonna find.
That's how I've seen it anyway, I mentioned it's fun on single target because in that situation it really works but it gets messy on sustained AOE. When we're deciding "ok it's time to drop carnage for Dragon Roar" on single target in combination with frenzy stacks maybe it's going to start feeling messy from ability bloat and that short enrage duration. But I think Fury is different to Arms, Arms is not fun for anyone and has frustrations that will annoy everyone on multiple levels where as Fury has more isolated frustrations and the general player will probably like it.
That's how I see it anyway, unless we see some drastic swings in in playstyle/performance of the specs I'm going to be playing Fury in Legion primarily.
I disagree, in PVP that might be useful but in PVE (outside of possible isolated situations) you will prefer Carnage or Dragon Roar, it's already possible to put 2 rampages into 1 reck while using carnage, and carnage is increasing your enrage uptime/damage throughout the whole fight and not just during reck. Our other Warrior also running Fury last night bemoaned his decision to take reckless abandon as I completely crushed him on dps by running carnage.
