Of all of the weapons the spear is one of the oldest ones, think about it, its a long skinny pole with a pointed end. It may or may not have metal pointed end and still is effective. It is not complex to teach someone how to use it as it is simple weapon, yet how many martial art schools teach how to use it or even throw it. I know some Kung Fu schools do they make it a bit fancy, I know groups like NAWA do and spar with them, the Hawaiian Lua schools do but only a hand full of FMA schools even still teach it. I know some of you are saying when would I every carry a spear or lance but when you think about it the principles use are used with a rifle with bayonet. Used in group they will make people turn and run and yet there are martial art schools will tell you it is obsolete weapon. Funny the military still teaches this weapon usage. Anyway just my thoughts.
