My dps on my dumner MagDk was the same as live
.
Now keep in mind I am bad and someone better should probably test.
I also tested dual wielding swords on my dumner MagDK and my dps was actually really similar to staff but you do a lot less with your light attacks so me being bad might be a big deal but for semi-casual players the dps is pretty good with dual wield on a MagDK.
