Anyway, as an aside, how do people interpret the interaction between amputator rounds (gives felling, which halves TB on defence) and Eye of Vengence (gives bonus damage equal to the defence score of the target).
If Eye of Vengence's bonus damage is modified by Felling, then it makes the two essentially incompatible, or at least, no bonus for using both. It actually makes it better for a sniper to use expander rounds (-1 damage, but +2 pen) with Eye of Vengence, as at least then they get one more effective damage in.
Why do you think that amputator rounds and Eye of Vengeance wouldn't stack? The way I read it, Eye of Vengeance would add bonus damage first, and then when comparing the total damage to the enemy's defense, the amputator rounds' effects would come into play.
Because Felling directly modifies the defence value. Eye of Vengence uses the defence value of the target. Its an order of operations thing definitely.
