I'm using a warhammer at the moment (the manliest weapon in crpg) and honestly i wouldn't mind at all if devs would remove knockdown from 1h maces, but please, if you remove knockdown add some speed or damage to 1h blunt weapons( or both), because blunt damage is not as good as pierce, and most 1h blunt weapons are also slower than 1h pierce weapons.
I find quite retarded that 1h maces can knockdown people, and imo it's also ridicolous that the short black mace (2h?) used by many xbowers can knockdown too.
Also "cotton swabs" like spiked club, long hafted knobbed mace, long hafted spiked mace, staffs, Goedendag &co shoulnd't have knockdown imo, but obviously, if knockdown gets removed from those weapons, imo it would be needed to buff their damage and speed a bit.
Imo the only weapons that shuld have knockdown are: Mauls and bar mace (2h), long maul ( pole) and maybe also poleaxe's secondary mode.
P.s Bar mace knockdown chance is a bit too high imo, it should be decreased a bit.
