I just made an STF polearmer, using a scythe and peasant gear I was managing to get a 1:1 ratio by backpedalling a little, this was against some very good players without any previous training in polearms. If polearms aren't OP I don't know what is.
I am told weapons are balanced by the percentage kills by the community, which is stupid, since pole's best is Dezilagel and no offence to Dezi but his skills don't stand up to the likes of Bjord, Phyrex or Harlequeer Harlequin. Get rid of polestun, stop being "lazy" and balance by checking stats against stats, not by numbers of kills since 2handers have a much higher percentage of their players who know what they are doing.
