Polearms are weapons designed to keep enemies at a distance. In cRPG, a player needs only block once to come within striking range of a polearm user; from then on the effectiveness of the polearm decreases as it has lost the reach advantage (it is worth noting that this advantage is very small with the current 2h thrust animation). I had an idea while watching the right and left swing animations of the Elegant Poleaxe.
Here are two pictures of the Elegant Poleaxe while holding a left-to-right swing:
As you can see, the poleaxe has a blade on the end, that will arc in front of the player before the actual blade comes around. Here is an annotated picture of two pictures laid over each other -- one is the prep swing, and the other is mid swing.
This arc is just long enough to contact any player who is facehugging the polearm user. My suggestion: Any player that is contacted by this arc will be lightly nudged. The nudge is light enough that the nudged player will have time to bring up a block again, but they will have to be quick (or have a very lightweight shield).
This could also be possible with the overhead polearm attack:
EDIT: you guys are right, this suggestion would make polearms way OP. ¯\_(ツ)_/¯
