Posted my recent experiences in the feedback thread for Warriors.

After the patch last week, I copied over my main and leveled her again, deciding this time to do it without upgrading to r1 gear when I could to get a more accurate picture of Arms power in the leveling process.
Starting Secondaries:
At lvl 50 I had 44% Haste and 35% Mastery.
Ending Secondaries:
At lvl 60 I had 13% Haste and 19% Mastery.
Upgrades
To improve my character power, I had to downgrade some gear to get better secondaries because Arms is so dependent on them. I had to skip many ilvl upgrades because they would have been performance downgrades for the same reason. This is especially noticeable since there’s no ilvl scaling the first time around.
Secondaries
From my start to my finish the drop represents a massive loss in performance that could be felt hard because so much of the spec is passive. Resource generation is passive, a lot of the damage of the spec is from a passive secondary as well.
Going from, say, Haste to Critical Hit because it’s on an item and the item is an ilvl upgrade is a massive hit in performance. Assuming both gain and loss are the same at 2% then the Haste loss is a 2% performance loss in return for a 2% increased random chance.
Some loss in power is expected when you level. However, this is an absurd loss in power. The worst part for balancing is that it comes back in reverse once you gear up above what is set as the benchmark for Haste and Mastery, and it’s going to be even more absurd now that Arms has been returned to dealing front-loaded damage.
The end result is Mortal Strike used more often that hits for a high level of damage. This is right back to the standard of Arms underperforming at the start of an expansion cycle and the overperforming near the end as the Secondaries have risen in value far beyond what’s set as the benchmark.
The only way to solve this permanently is to give Arms active resource generation and make the Mastery just be a straight-up, individual duration, stacking bleed instead of adding more damage passively to the Warrior. The latter will give the Mastery Secondary Stat an ever-increasing value throughout the cycles.
