1.Of course i base my suggestions to realism.Otherwise add lightsabers instead.
2.Basically yes halfswording attack and block tecniques are closer to poleaxe fight rather than great sword fights.Usage of every aspect of the weapon,stronger stabs,surprise attacks,über balanced and powerful slashes...
3.All i say is halfswording is completely different and requires different training than normal sword fighting.If you want to use it properly,you should learn the tecnique (WPF) first.
1. Realism is useful as far as defining the setting and very flexible limits, balancing the game BY realism is impossible and would make the mod just crap. Ex: Making bows realistic would break the game, making armour realistic would make tincans nigh invincible, blocking with a 1h against a heavy polearm/2h would mean your bones get shattered, blocking repeated blows behind a shield would make your bones break as well etc.
oh and lightsabers are already ingame and they actually work better than old weapons did, for purpouses of
2. Unless you have studied halfswording manuals and actually used both techniques, your claim is based on only that halfswording uses polearm animations in game which is lol.
3. Halfswording is similar to regular 2h, you put one hand a bit further upon the blade - that's it. Try this - pick up a stick about 0.8-1.2m long (massive bonus points if centre of mass is heavily towards one side - like a 2h sword), then swing it with a 2h similar grip then with a halfswording one. Main difference between polearms and halfswording is that the centre of mass is placed differently, for a sword it's around the pommel area - for a polearm it's in a completely different place. Polearm techniques are not similar to halfswording, I'm sure that if you claimed this to an actual experts you would get laughed at.
Not to mention that it's a complete waste to put wpf into both 2h and polearms JUST to use halfswording, I can't recall the last time I actually saw anyone use in a battle or a duel, probably months. I really pity anyone who actually put wpf into polearms to use halfswording, imo.
