Monk Weapon Choice High AC Mobs

[Stonewallx39]

Hello, I’m looked to better understand how to choose between a solid 2h blunt weapon (like T-staff, IFS, or Peacebringer) and epic fists when fighting higher level Velious mobs/raid mobs. Strictly in the DPS sense, in the case I’m not pulling at this point ot taking any hits.

I’ve heard for the highest AC mobs to use weapons that rely on damage bonus for majority of DPS, is there a rule of which mobs should be thought of as “high ac?”

What about in the offhand? If I use epic fists should I bring SoS for ratio (since no damage bonus of offhand?)?
