With pikemans valor it was not bad, and with the high HP it was a great way to catch people off guard - much like the spanish inquisition, nobody expects dwarf-polespec. Keep in mind, felars do well with it, and they're smaller than a dwarf - dwarf is human sized if I remember right - so with one pikemans valor you get checks where you defend like a giant.
Loved slice with the edge that made it more damaging/bleeding - it was a great kill sealer in the low/early midrange. Chop still worked well, so did entrap, slice was reliable, and legsweep was the tits. Keep in mind, this is coming from me - and I'm not even good at PK. Water vuln sucked against some, but for the most part wasn't an issue.
