Oh god get Stormstrike first, wy? it means if you normaly attack 3 times in 10 seconds with a 2h you get another attack or about a 25% increase in dmg (zomg thats a bit)
Daul wield believe it or not will suck when you first get it, how much gear at that level has a good amount of hit? I would not use 2 weapons until level 44, when you at least have 6% more hit from improvements.
Even then, I can not understand why anyone would want to DW very often at lower levels, to be honest it seems like a waste to me, when you dual wield without gear, you will see many miss miss miss... Besides, at such low levels we can more or less destroy most enemies in just a couple attacks with a good 1h weapon and a nice WF... maybe i am just too old school, but at lower levels I tend to like burst damage so stuff dies too fast for it to be a problem.
If you do decide to DW, please get weapons with matching speed and they need to be as slow as possible (without sacrificing too much dps), why you might ask, weapons with matching speeds make flurry work better, and generally the slower a weapon the higher the top end damage, not to mention WF has that dreaded cool down still.
