Current Behaviour

Swing timers while dual wielding weapons of the same speed are always synced and they cannot be desynced, and that allows offhand autoattacks to suffer from the dual wield penalty while queueing on-hit attacks (cleave, heroic strike)

Expected Blizzlike Behaviour

Swing timers while dual wielding same-speed weapons should be desynchronizable, and the warrior's offhand autoattacks should not suffer the dual wield penalty while queueing an on-hit attack such as heroic strike or cleave

ُEJ thread. i will only post the tldr but i recommend reading the full EJ report
In-Depth Fury DPS Discussion, in depth explanation of the said unique interaction

Offhand swings that land while HS or Cleave is queued do not suffer the DW miss penalty. They're treated as if you were single wielding when the swing lands. Example Saurfang parse with 1 melee miss over the course of the fight (possible if I couldn't HS every swing or re-queued HS late, likely at the start of the fight and execute range): World of Logs - Real Time Raid Analysis

Steps to reproduce the problem

1. download a swing timer addon and a damage meter addon, create a warrior, dual wield two same-speed weapons and go to the nearest enemy or target dummy

2. spam queue heroic strike and look at the swing timers
