You could use it on a Charge Paladin or some other character where speed is important, or use it as a keepsake. It is, as said, unfortunately too slow to be better than an IK Maul or similar weapon. It is kind of pretty though
All the original classes are represented except for Necros. So, in typical fashion, the pasty guys got shafted out of a job. If there was an act 4 merc, it would be a necro, though, with Bone Spear and a few different curses act 2 merc style, if I had my way.
