Just following up here to see if this idea makes any sense:
For example, I created a MechWarrior who has, according to their MechWarrior character build, a 2 skill level for piloting and 3 skill level for gunnery. I also used the standard BattleTech rule book to roll random piloting/gunnery and got a 5 for piloting and 4 for gunnery. So, I have both of these on hand for this character.
On the battlefield, could I create rules where 5/4 are the base values for this MechWarrior, but the 2 and 3 skill levels act as roll modifiers, reducing piloting and gunnery skill rolls by -2 and -3, respectively? Obviously, this would lead to optimally low to-hit modifiers.
