It seems like lightning attack for melee and full auto for range are the way to maximize damage leaving solo shot weapons like missile launchers and plasma cannons in the dust. Not only can you score multiple hits, but it makes it harder to dodge as well since they're are likely to need multiple degrees of success and not just one.
Would it rebalance the scale if weapons with accurate had to be dodged by degrees as well? So if a player was hit with enough success to get both bonus d10s, he'd need one dodge to knock off 1d10, 2 dodges to eliminate the other bonus d10, and a third to negate the base hit.
Also what about letting some using aim change their +10 bonus to hit into a -10 dodge for the opponent?
