Fury Warrior Frequently Asked Questions — The War Within (11.1.7)

Generally, no, as long as you are using Rampage regularly. Because it is the only spender, Fury does not have many issues managing Rage. A minor optimization can be made by delaying Rampage by a single global cooldown if Enrage is already active in order to generate extra Rage, so long as it does not cause you to overcap.

No. Off-hand attacks deal 50% less damage than their Main-hand counterparts, reducing the reliance on keeping two completely competitive item-level weapons, although it is still an important gear slot.

When possible, but not at the expense of other uses unless they are hitting multiple targets. Stacking cooldowns is important to dealing effective damage, but this is really a matter of timing. Regularly delaying a 60-second cooldown to align with a 90-second cooldown is almost always going to lose more damage than it gains unless its to hit multiple targets when it would otherwise hit only one. There are exceptions to this, especially when delaying by minor amounts, such as delaying the 45-second Odyn's Fury by 5 seconds in order to align with an Anger Management reduced Recklessness, but those decisions should be made in the moment based on how much longer the encounter is expected to last.

Due to the number of variables involved, the typical answer is to simulate it for better accuracy. Between gear, set bonuses, trinkets, and sometimes even talents, there is no such thing as a one-size-fits-all, though item level is typically a good indicator due to primary stat being worth much more than in previous expansions.

The only exception to this rule is when a specific fight dictates a certain set of optimal talents and gear pieces that enhance their strength. If you are curious about what kind of setup to go for a specific fight, WarcraftLogs.com's rankings and statistics are a good place to see what others are doing.

We have a guide on how to sim yourself here:

More is better up to a point. Each stat begins to suffer a small amount of diminishing returns upon reaching ~30% (made up of rating, not considering % increases like Enrage), which is meant to help players diversify their stats and make more pieces of gear potentially useful, rather than only ever wanting to stack one stat. How much this matters can vary wildly depending on the situation though, so it is difficult to give a concrete answer that covers all of them. Simulations do account for this though, so that is typically the best guideline.
