I don't know if this was brought up here, but to me one of the reasons I have been looking at 'alternative' weapons to all the others is both a feeling for something more unique plus a little bit of a challenge.
I have done enough with Greatswords, Composite Longbows, Rapiers and all the other top-of-the-line weapons that I have been wanting to work with the other stuff that most just go pfft and toss in the back of the loot pile.
It seems more and more that for these other weapons to be put on a similar level to the optimized ones is to work at it through class features like the Bolt Ace in regards to crossbows rather then to redesign the weapons it seems unless PF Unchained does something with them.
