Lethal Hits vs. +1 to Wound (MathHammer question)
Do these two bonuses have statistically the same effect?
I play Blood Angels, I always used to think of a chaplain (+1 to wound) as the offensive leader option for my death company, and Lemartes (-1 to damage) for defence. But I was playing around on UnitCrunch for fun (yes I'm fun at parties haha) and I realised that since Lemartes also gives his unit Lethal Hits, their damage output is basically identical. Weird coincidence for one defensive profile, or is it true across the board?
My thinking is Lethal Hits gives a 1/6 chance of an automatic wound, +1 to wound gives a 1/6 chance of turning a fail into a success, so they are basically the same. Does that make sense? Or is the math different somehow? If so which one is better?
