Sudden scarce of Damage

Early mapping. Phrecia, Boneshatter of Complex Trauma, Marauder/Commander.
If map has mod "Monsters cannot be stunned" my damage beginning evaporate and become 1/4 of normal damage. It happens every map with this mod.


May be i can't realize something.

It'd make sense to have slower clear, due to the loss of Boneshatter's damaging pulse.

Melee hits with Boneshatter that stun an enemy release a damaging pulse, which has a larger AoE depending on the length of the stun. If the monsters cannot be stunned, this cannot activate at all.

I don't know how much that'd affect single target though, aside from losing damaging pulses from hitting a rare surrounded by minions for example.
