Needs to consider if weapon is an alt weapon for aim and accuracy as well as functionality

Need to consider range?

Grenade Primary and alt as well as Scavenger alt need to take into account gravity

Needs to pick our new weapons correctly to determine which ones they should:

decay aim purposely (instant hit weaps)

shoot "around corners" (bouncers, mines, splashdamage?)
