The decision to make most of the short swords 0 slot in the last patch was a good one, in my opinion. It opened up the possibility for new builds/loadouts while simultaneously giving people an incentive to try out a lot of decent weapons that had previously been ignored.
I would like to propose that a similar change be considered for 2h and polearm weapons that fall within a specific set of criteria. Basically, any 2h with both a weapon length of under 100 cm as well as a weight of under 3kg should be 1 slot, while any polearm with both a weapon length of under 150 cm as well a weight of under 2kg should be 1 slot. The weapons that would become 1 slot with this change include:
Axe
Two Handed Axe
Battle Axe
Two Handed War Axe
Studded Warclub
Katana
Boar Spear
Spear
Furthermore, any existing weapons that already fall under these criteria (ie Mace, Staff, Quarterstaff, Shortened Spear, Military Fork) should, if necessary, receive minor stat increases to make them competitive and balanced with the weapons that would become 1 slot with this change.
