5.4 arms is propped up on deep wounds and slam buffs. We scale extremely hard off weapons (502->509 weapon alone is like another 5k dps), but the only secondary stat that helps us is crit. We get basically nothing from haste and mastery. They even removed the only benefit to mastery in aoe lol
We’re also benefitting from the random buff to overpower. It synergizes stupidly well with our 2p tier (25% ms dmg iirc) since op reduces the cd of ms and 3 op’s in a cs window is now better than 2 slams.
