So if you put WF on your mainhand, and FT on your offhand your DPS would actually increase?
No. This has been mathed out by several Shaman over long-term periods. There is absolutely no conceivable combination of buffs that will yield more DPS than WF/WF.
The idea sprang up from way WF works with weapon speed and the cooldown. Lots of people started thinking way too hard and decided that the weaker (and usually faster) off-hand was "stealing" procs from the full power of the slow main-hand. It makes sense logically, but the idea that WF/FT or WF/RB yields more DPS is a myth.
Now here's some counter-logic for you:
For starters, no matter what weapon arrangement it's on, WF procs at a 20% rate. That's one out of every five swings. On a 2.6 speed weapon (the optimal main-hand for DW), WF will proc an average of once in 13 seconds. That's a pretty generous window for WF to proc on your off-hand and still not "steal" procs from your main-hand. In fact, you probably won't notice your main-hand proccing WF one bit less often when it's on your off-hand.
What you
will notice is that Shamanistic Focus, Flurry, and Unleashed Rage are up more often. See also: constantly. Both extra hits from a WF proc count as a physical hit from you, and if either of them crit, all three of your crit-proc-based talents will activate. That, coupled by the simply higher raw DPS of WF/WF overtime, is going to yield more DPS than any other combination of buffs you could try out.
Honestly, you don't have to take my word for it. Just try it. The next time you raid, try WF/WF if you've been using something else or WF/FT if you've been using WF/WF. You should notice an increase or decrease in your DPS respectively.
