Return of Reckoning

A short proposal about the choppa tactic Was Dat Yer Finger?
Its from a AoE choppa point of view. Ive read that the Dev team got plans for Chop Fasta! So I decided to focus on this tactic instead.

Could this tactic if it where to debuff anything else than Weapons skill help out with choppas AoE struggle?
Making them bring more than just damage in a warband.

So what I would like to discuss is what other stat could it debuff (if its possible to change) to help out choppas with AoE but at the same time being balanced and a good tool for choppas.

Some ideas:

Initiative?

Willpower? To help out your ranged dps with disrupts and reducing the healing done by enemy healers

Wounds?

Armor?

Any of the Resistances?

Reducing the enemies chance to do critical hits?

Please format this correctly, detailing weaknesses of current iteration of skill and your proposed solutions, as this isn't really telling me anything.

Locked.
