-You have one of the best disarm weapons in the game possibly only second to
whips/flails. Better in some aspects because you can entrap blind. So I am
not so thrilled by the idea of Crashing.

-Having played a few polearm specs I would strongly suggest Incarnadine Wave.

5) polearm
You seize an exposed flank, and are greeted by a satisfying gush of crimson. (bleeding)
Through the Incarnadine Wave, you time a lunge to push XXX off balance! (lag)

Those are two nice to have in combination. Doubly so if you are a Felar since it will be coupled with:

10) hand to hand
Flowing through the Incarnadine Wave, you precisely time a vicious swipe! (dam)
Flowing through the Incarnadine Wave, you strike a vulnerable point! (con)

You do not even have to take Hand to Hand spec to get it to work! Even my Elf polearm spec
got Wave results with hand to hand when disarmed.

-Space seems interesting depending on your second weapon choice. Mainly on how much maledicting
or straight disarming you can do. Daggers do not work well with Incarnadine Wave but maces/axes/whips/flails stack
quite nicely.

-Finally it is all about your playing style. Rarely do polearm specs stand and deliver huge damage unless you
are playing a giant. And with a giant race there are just so many more devastating weapon combinations that
simply outshine polearms.

I love the versatility polearms provides in that you have one of the most interesting and opponent frustrating forms of
defense: charge set. With it perfected there were only a very few attack types that I could not set. Ambush,
blackjack, impale, underhand are all fun charge set since it turns the starting battle more in your favour. Especially
if they are the flee and return types then they have nothing but pain. Also slice is simply amazing with the
edge and your straight out defensive abilities makes ranking a breeze.
