I try to include some BC rules within my DW campaign. After using the BC rules for ranged attack (single shot +10, semi +0 and full-auto -10) I wonder about swift and lightning attack.
I like the idea to treat the melee combat similarly to the ranged attacks: Degreee of success indicates the number of hits.
But now I wonder if lightning attack is not too powerfull. Let's say you have an assault marine (WS 50) facing a huge target. Since lightning attack (-10) is a half action the player can also choose to aim (+10) and since the enemy is huge another +10 bonus is granted. Thus it is possible to make as many hits as with a heavy bolter?! If you go for two-weapon fighting it is even twice that number of hits?!
Even if the weapon properties lead to a lower penetration the bonus damage becomes also incredible high!?
Do I miss something or is the BC melee system not meant for DW?
