I'd like to see all weapons over 145 length, unsheathable. Maybe in addition, lower upkeep significantly on spear based polearms, and raise their stab damage a bit too.
What I think this would do, is more people would grab a utility spear, thus lowering cav effectiveness (alot of people complain but cant pinpoint why they feel Cav is OP - evereyone/ alot more people carry spears, and learn to use them - Bam! Cav nerf, without nerfing the class AND a more realistic looking battlefield.)
The whole unsheathable thing, would force people who where real hybrids to throw thier 'reach' weapon to the ground, and deal with inclose more realistically, without an unrealistic switchout at will, which would, flow-wise resemble a REAL melee battle much more.
Also, make running with any weapon over 145 length, and over 'a certain' weight, affected with a larger penalty, so that the max running speed with a long heavy polearm is more realistic and nerfed.
And while your at it, take away the stab length on 2 handers. AND possibly, lower the amount of damage a bit on their Stab ONLY.
It would give a boost to the dedicated 1 handers also, that do alot of dirty work, and dont get as many kill opportunities as they would on a real battlefield in general. Not a numbers type boost, but a boost relative to the other classes, because the cav now is dealing with more spears, and all polearms guys, from dedicated, to support, to back-up weapon, are now dealing with non-sheathability and max running speed nerf.
Then you would have the dynamic of all classes of polearmers deciding when faced by an incoming wall of shields to either fight with less running speed,
OR if its just a anti cav stick/back up for less outnumbered situations' - drop that long pole and run for it -more like in rl,
Press play, and see what happens.
Meh, just thinking outloud, heh.
