Added one handed weapons + dual wielding. Different weapon types have different attack animations. If you have two different types of weapons equipped (for example an axe and a dagger) They will each use their own attack animation. When dual wielding the server manages a players two "arms" separately with separate cooldowns and attack speeds. the offhand weapon has a 30% attack speed penalty. When the one "arm" is ready to attack at the same time (or close to) the other "arm" the server will make the one wait a bit but it will make that "arms" next attack come quicker to make up for it.
A video and some screenshots.
