Question about Defiance, Wrath and Infuriate

[Naberrie]

I'm just starting MRD, looking to take up WAR. My FC has a lot of PLDs but no WARs, and I wanted to be able to bring something to PTs aside from my BRD if needed. Right now I'm only 18, and really enjoying the class. I've been looking ahead at the skills and have some questions.

The Defiance description says: "Using certain actions while under the effect of Defiance will grant Wrath.
Each unit of Wrath increases critical hit rate by 2%. When five units are stacked, you will become Infuriated.
All Wrath is lost when Defiance ends."

Looking here, the only skills I can find that seem to fall under "certain actions" are Storm's Path and Storm's Eye, which come at 38 and 50, respectively. So, as far as I can tell I can't even use an action that grants Wrath until 38, eight levels after I get Defiance, which seems weird.

Now, at level 35 you get Inner Beast, which it says can only be executed when Infuriated. But it seems that you can only get Infuriated by either using Infuriate, the level 50 job ability, or stacking five units of Wrath, which you can't do until 38 when you get Storm's Path.

I'm hoping I'm just missing something here. Because the skill descriptions don't quite seem to make sense.

Butcher's Block will give you wrath, Maim will give you wrath, Storm's Eye will give you wrath, Storm's Path will give you wrath, using Vengeance will give you wrath... trust me, building Wrath is pretty easy and you can do it as soon as you get access to Defiance. Infuriate is useful, but not needed until 50.

You forgot Skull Sunder which also give a Wrath stack.

Certain Actions: Skull Sunder (after heavy swing), Butcher's Block (after skull Sunder), Maim (after heavy swing), Storm's eye (after Maim), Storm's Path (after Maim), Vengeance, and Berserk. It generally takes 20-22.5 seconds to build up to 5 wrath. Slightly more before you get Storm's Path.

Okay, awesome. I was hoping it was just a matter of the descriptions not being complete. Thanks.
