I think that is the whole point of my post(s) in the first place. As c45 pointed out above, Arms still crushed Fury on most of those fights. You are right, they were closer to equal than ever before and the sole reason is because just like now, Arms was buffed out the ass to make it better.
This really comes down to simply how I feel about things. Arms is not an engaging or fun spec for PVE. Give it some design overhauls, make it actually enjoyable to play and I'd be a little happier.
Completely off topic; If I was making decisions, I would make Arms the go-to PVP spec, Fury the PVE spec. Its simpler on design, simpler on development and easier on players by removing constant decision and theorycraft, along with in raid regemming/reforging. To be fair, I think that applies to all classes, not just Warriors. But since we are talking about Warriors. All damage equal, Arms will always be stronger than Fury in PVP. You never hear people crying about Fury being viable in PVP, you never hear Rogues crying about Sub being used in PVE, why all the disgruntlement about Arms being used in PVE?
Likewise, for the people who say "but Rogues have 3 specs". Pure DPS specs get 1 PVE spec, 1 PVP spec, 1 "support spec" (think BM hunters getting extra buffs).
Hybrids get just that, ability to fulfill multiple roles and different playstyles. Warriors would have Fury - PVE, Arms - PVP, Tank - both.
This obviously would take a ton of work, and reorganization of gameplay, such as removal of many class wide abilities; raid cooldowns would be a "support spec" spell. It's simply an idea I like to bounce around in my head.
