Maybe I should comment a little bit on the purpose of the build, since you have received other suggestions as well and maybe you’re wondering what’s what in the grand scheme of things.
The build itself is designed to work with literally any handmaiden melee weapon that isn’t a shield. The only tweak you ever have to make in terms of melee is to switch to thp on kill if you ever want to use the 1h axe. The longbow, its properties and the configuration of the charm are designed to help you reach the most ranged breakpoints in Cataclysm, if you will ever be interested in venturing in that difficulty. You can 1shot bodyshot an assassin with a charged shot, 2shot bodyshot most specials with charged shots and 1shot headshot any special or stormvermin with a charged shot.
The traits and properties are selected for what is most relevant in the game and will give you the most bang for your buck in terms of overall effectiveness in a variety of situations. The talents are chosen with the same goal in mind. Having an aggressive build with a large DPS is always going to make your life easier than other alternatives. Here you can all by your lonesome crank your crit chance up to +40% and your attack speed bonus up to +70%. In these circumstances, the handmaiden becomes a ridiculous blender that can chew threw mixed hordes, can fish crits with light attacks to ignore armor and generally has a very easy time to gain or maintain initiative.
Also, since you are not using invisibility you never run the risk of smashing your own team when enemies randomly switch aggro on them. You need to be a little bit careful with how you dash, because not having invisibility means that enemies continue to aggro and track you even mid-dash, but what this means for example is that you dash through a horde, turn to face it, block or dodge out of their running attacks, then you execute your own push-attack for the attack speed bonus and you commence delivering the pain train.
Since you want to use the greatsword and in case you didn’t know this, the charged attack has a follow-up slash that is pretty useful. You get it by executing the heavy attack followed by a light attack, just as you do with the glaive.
