On its own, that sentence is definitely confusing. The way it is worded sounds to me like I would roll 3 dice and a success would be whatever the potential damage I would take. (I have to do an Armour Check against 2 damage, so I'd roll 3 die and a success would be 2+)My thoughts exactly.
So the rules are the same as in Dreadball 1st edition, right? The difference between the attackers and the defenders successes is the ammount of wounds the defender has to block with the armour check (if the attackers successes outrank the defenders'). The armour check is a 3 dice roll against the defenders' armour stat. Every success geds rid of a wound.
