Talking, for example, about BML-G2 P05MLT-10 - the 10-cell direct missile launcher. Compared to a simple, light, starting 4-cell one - it has about the same dps; applies much less pressure, allowing to regen all the impact during downtime; has an impractically-long lock-on time; and, after all, weights much heavier! What are its advantages then?
I want to run an action "bolter-porn" oneshot about spacemarines. Distinctions will be the chapter tactic, and marine's specialisations (i. e. Assault marine can use jumpack, and is good with explosives). I have decided on the attribute list - it will include Might, Focus, Tactics, Materium, Immaterium, Humanity. I struggle to come up with the second prime set.
I dont think focusing on skills will make sense in a high-power setting. I am thinking of making a set for equipment - so, Melee weapon; Firepower (bolt pistol is d6, heavy bolter is d10), Armor (Scout armor is weaker then usual), etc... but equipment is transitory and replacable. What do you think - is it a fitting category?
