I see that sim has tendentious to use slower and stronger (with more damage per swing) weapon as off hand instead of main hand like:
- Every ability strikes with Main Hand.
- Stronger Main hand with Whirlwind, Cleave or Overpower doing more damage.
- Thx to HS/Cleave queuing faster Off hand should hit even 2 times with extra hit chance.
Also very often i see Hanzo Sword as Main Hand that makes me curious.
