Add a poll so I can vote no.
Most players will have their block ready before the swing is released. If there is a "auto nudge" on every side and overhead swing. Forcing all opponents to re-do their block right before the actual swing even contacts them sounds absurdly overpowered. And the reaction time would probably be too short for players with 100+ pings to be able to regain their blocks at all.
Have Tanken or Sauce show you the jump-spin-stab.
This is all provided that they are facehugging, if the player keeps his/her distance from the polearm, he/she won't have any problems with the nudge.Kicks already provide a way to punish that. Long weapons do not need another way to keep people at range.
... especially after sneaking up on a archer, try pushing people off edges...
Polearms are weapons designed to keep enemies at a distancecorrect, isnt that the thing this game fails at the most to recreate?
