// TODO: Other class skills...tried this, gunzerker broke me
// TODO: weapons need attributes like grenade reloads
//       EDIT: grenade reloads are based on remaining ammo...so calculating
//       this damage would be a one off value? magazine size minus one?
// TODO: calculate things like explosive AR where there is no bullet damage :(
