I have a +3 Ranseur, +3 Spetum, +3 English Bill and have previously played with a +3 Swiss Halberd and +3 Long Awlpike.
I wouldn't call any of the above completely useless, they're decent weapons, but they are too weak compared to other weapons. There's pretty much no reason taking any of the above instead of a long spear, ashwood pike (with shield) if you don't mind one less attacking direction or the glaive or german greatsword if you want 2 more. No stat on them justify what you lose either way, and especially after the two turn-rate nerfs, they really aren't up to scratch. It's quite sad really.
