should i use sword in main hand, and dagger in offhand?

[andrewx]

should i use sword in main hand, and dagger in offhand, or both daggers? i read some threads in here, and i think i wanna level in the combat tree. i see in AH that exists an one handed sword (Defias Rapier), with 1.6 speed. wouldn't that make it a dagger, since it has such a quick auto attack?

I'm assuming this is for leveling - you want a slow sword/mace in your main hand, and whichever weapon gives you the best stats in your offhand, doesn't matter what type it is.
