DONT USE BASTARD WEAPONS WITH A SHIELD UNLESS YOU ARE BOROMIR
They become super slow and super weak. You may want to use a small, disposable shield if you're terrified of archers, but you should never use a bastard weapon with a shield unless you are on a horse, and even then its not a very good idea.
It is much more practical to invest all your WPF into a single skill so you can effectively spam with a weapon type instead of spreading WPF thinly over several skills. Unless you have a lot of Weapon Master, use only one weapon type.
