Hey I've recently tested a house rule i made with my team:
After playing a module, we were a bit frustrated by the fact that your skill with a weapon had no impact on how much damage you did. The only way to increase damage output was to either roll high on the damage roll itself (luck), chose the most damaging weapon available, or to chose weapons capable of autofire and even semi-auto fire as skill with weapon (BS) and situational modifiers almost directly increases damage output.
House rule: For every degree of success with a single-shot weapon, you can add one to damage (maks +3 damage).
I also allow this with melee weapons, but only when single-wielding.
What do you think? This makes the damage output of characters wielding pistols and pump shotguns (or even autoguns fired on single-shot) a bit higher, but not even close to what those who use autofire gets (especially with the inceased chance of Fury).
I've seen the rules for extra damage with accurate weapons in the errata, and will not allow those extra damage dice to stack with my rules.
