How many people actually used spears in previous games?
I did. In fact, polearm and throwing weapons along with crossbows were pretty much the only things I used in Morrowind...
They looked pretty polished in the gamejam vid, but from a business perspective, it would make sense for them to put them in as a selling point in a future expansion. I mean come on, people have wanted them back since Oblivion and if you don't play on a PC and mod them in, what can we do but request. And request. And request and request.
