Spears are one of the two longest used weapons in human history, next to the axe. The first ones were wood and flint, the last ones were used up until the age of gunpowder.
gotta disagree on you there, what about the blow dart even though you do not always shoot the dart, you can attach a bayonet to it, and they are extraordinarily long.
or do you use for the longest amount of time, then I agree with you there, I do think clubs have gotta be up there though we have been using them since cavemen and are still using them
they probably will include spears, I think they probably redid the system so that you can use a weapon with any animation you want, like Fallout
they also should have throwing knives, I could care less for shurikens
