I take issue with the base characteristics for the ranged heavy and melee combat skills. Ranged heavy, current agility based, should be based on brawn as it take more effort that agility to hold a heavy two handed weapon correctly, then ranks would improve aiming ability etc. Whereas a light single handed weapon can easily be picked up but requires more coordination to steady it and fire, again ranks adding efficiency.
Similarly melee, currently brawn, should be agility based, melee attacks such as kung fu are more agile and differ from brawl attacks like boxing which are more brawn. Similarly weapons should be more carefully classified, a combat knife as a melee weapon could be used like Jason Bourne's biro and based on agility. The truncheon however should be mainly reclassified as a brawn weapon as its main usage would be to bash and based on brawn.
