The easy answer is that Blackout Truncheon is not a good Enhancement weapon no matter what proc it has. The 1.5 speed ruins it pretty much. I'd say you're better off sticking with what you have. And I wouldn't say that's a question that can't be answered elsewhere so as of yet this thread has no meaning.

Rapparee: Thanks for your help. I would enchant mongoose after I get the 2.4 badge items since crusader is vastly cheaper than mongoose, and I don't feel like dropping a mongoose on my green mainhand too. At that point of posting I do not have fury yet. For my other gear, I would enchant once I get epic versions from Karazhan and ZA.

I find the Yo's simulator hard to use, due to the fact that I would have to manually input stats every time I use it,quite tedious especially since I also have to calculate the rating to % each time and add it up too. Is there any 3rd party script that is written that could remember what you keyed the previous time and just auto input for you?

If you're going to run one with the intent of finding your "true AEP weights", I would recommend leaving your computer on overnight and running Yo's simulator in its own Firefox window with nothing else open. Run it for 100,000 hours, as this accomplishes the same thing as running it 10 times for 10000 hours and averaging the results, and you won't have to babysit it. It's not really freezing your Firefox, it's just running in its own thread so Firefox handles it poorly if you try to do anything else in that Firefox window while it's running. In addition, make sure you're not running WoW while you're doing it, as that really tends to freeze things up.

Basically... do the all-night test as I recommended and you'll have your "true AEP weights" waiting for you in the morning.

Uh, Daler? I see the point of this thread is to explain Theory that's been covered everywhere but is hard to swallow. Let's keep the thrash out of the Theorycraft, allowing those who don't want to repeat themselves to keep their minds on more important tasks.

I, however, am a windbag and love to repeat myself, so here goes.

The reason 2x WF is superior to 1x WF, even though some of your WF attacks are smaller offhand attacks, is simple: when you have WF on one hand, the chance for that one hand to swing is 20%. However, when you put WF on BOTH hands, EACH hand has its proc chance increased to 36%.

So in essence, you're not getting twice the chance to proc WF, you're getting about three times the chance.

What's more, no matter how many hands you put WF on, it now has a 3s cooldown in between procs. That means you'll never hit a 20% proc rate with any weapon slower than 3s -- the first attack after a windfury has a 0% chance to proc. Thus, this tripling of your chance to proc WF actually improves your damage from MH WF procs, too! (The Main Hand has a natural advantage to proccing Windfury, regardless of weapon speed, because Stormstrike always evaluates the main hand first).

Neither of these divergences from the tooltip -- the 3s CD and the 36% chance to proc on either hand -- are documented publicly by Blizzard, but either is easily detectable in any combat log. They've been around since patch 2.1, which I believe is a year old.

You can see this first hand without doing any theory. Get a copy of Recount, then go farm with WF MH and FT OH, then farm with 2x WF on some slow weapons. I guarantee you will see more DPS. And as your gear improves, WF just keeps getting better and better.
