I am currently going with a polearm build, and loving every minute of it. The reason I close polearms over the supposedly OP two-handers is the versatility. High-end Two Handers basically have cut damage and the ones with blunt/pierce really dont fit my style. I love killing tin cans, so I grab my trusty bec de corbin and can take out most tin cans in 2 -3 hits. The pierce damage really helps. I never really have a problem being outreached either. I guess my studded leather coat is light enough that I can stay in range most of the time. On top of that, put a few points into horse and you can secondary as a lancer no problem, as the wpf is already there. Grab a pike, and you are the best melee support in the game. Sure, two-handers have insane range and speed and can lolstab, but all that can be countered by blocking and getting up close and personal.
So to all you polearm users out there, do not give up hope, polearms are still very effective IMO.
