If you like stabby things, you should stick with the shorter ones. They are the easiest to stab with. Although, if you want a sword that is balanced I would go with the
Side Sword. High speed (Nerfed) with a decent length. It does equal damage in both cut and pierce as well. A decent sword for using with or without a shield.
The only problem is that it is expensive. Although, if you want a decent replacement you could try the
Arming Sword. Everything is the same but the pierce damage is a bit lower. It is a lot cheaper to maintain though.
Or if you want a happy medium. Go with the
Italian Sword It has great length, can be used on horseback effectively. Good cut and decent pierce. As well a good speed to go along with it.
I would also like to add that the Italian sword is hard to see in some situations. Making it harder for some to block.
Well I try to use it a lot in Native I use short swords and stab a lot but it is harder in cRPG and many of the skilled players just down block every single stab.
To land a stab, you will have to start being creative with your swings. A lot of Crpg players are experienced. I usually use stabs on enemies that are being attacked by many players at once, or if I sneak up on them. I more or less just like the speed of short swords personally.
