What to do?

So, what to do when servers are down for maintenance? Thats simple, browse the web for answers to your wonderings!

Personally I was reading a little on MMO-Champion and looked on a few hunters I know are better than me on the armory. Then it hit me, why are some hunters dual wielding rather than using a 2hander?
As you would know if you read my blog, I have a pretty decent staff from LK 10man normal which isnt too hard to get, especially after the +25% stat buff in Icc.
Yet I see many hunters dual wielding weapons like Hate-Forged Cleaver or Havoc's Call, Blade of Lord Lordaeron Kings. I cant seem to find threads anywhere about same question as mine or a thread explaining why this happen.
So I made my own on the European wow forums, asking why ppl dual wield.

I look forward to see what happens, cus again, I tested out the spreadsheet to see the differences between my staff and those weapons, and I see that my agility is higher when using 2hander aswell as my dps.

What do you think?
