It feels pretty bad right now. I've been using a +3 shortened spear and it's pretty rough landing a stab right now. Last night there was a pack of throwing lance guys on last night and they kept bouncing their stabs on me. I only wear 49 body armor between gloves and shirt, this combined with the flat nerf to stab delay puts polearms in a bad spot, when it was relatively obvious that 1h needed the most delay, then 2h and then polearm. So, you've effectively ruined the polearm's main strength and like kafein said it's just been left with horrible swings. To top things off, my teammates seem to be walking into my backswings a lot, so I basically can't do anything, and now I'm angry I made a pole/arm thrower hybrid. Hell, I've been more effective meleeing with my HTA than actually throwing them or using a weapon I actually have WPF in.
The one good part of this is that long spears and pikes are a lot less wonky now.
