Back in medieval times, only best knights deserve 2H sword - true elite
So if you have 100 knights. maybe 5 of them deserve 2H sword (those who were close to the king or something). Why? Because it is expensive sword to make and you need extra training lesions for it.
It is long and perfectly balanced deadly medieval weapon, and you can do so much more things than with 1h sword, polearm, spears and so and so.
Simply it is the best medieval weapon you can get.
Never understand why so much crying here about best medieval weapon. Status of 2H swords is nerfed right now. They can make much more damage and they are much more longer in real life than in cRPG.
All others weapons in cRPG are buffed so they can be equal to 2H swords.
For example: IRL if you go with spear on 2H sword, knight will easy cut wooden spear in peaces and kill you. But, this is a game .... yea right. Just stop QQ about 2H swords.
