My first time actually seeing the polehammer... eww. They shoulda used the model I provided years ago, looked like an oversized bec combined with a meat tenderizer, but it was sexier than... that*.
*If only because it was more hammer, less spikey thingy. It's called a pole
hammer, after all. Also it was intended to be a lighter-weight, shorter and faster crushthrough weapon for polearms, similar to how 2handers get multiple crushthrough options. Not saying this polehammer should get replaced, but I think it'd be cool to finally offer something that fills that niche in poles.
