Unchained, when do I use it?

[Marxam]

Oh, I would also like to add this: When you are standing in front of a boss before the pull and you are waiting for the healer or DPS to get ready and you are sitting in 5 stacks of wrath and watching them tick away, if you have just a few seconds left, popping unchained is a great way to use up those stacks and not let them go to waste, so when you rush at the boss you a have a really decent way to front end your damage and establish loads of threat right from the get go.

A good point but what I do now is Steel Cyclone then switch to Deliverance + Berserk. However I only used Unchained now when I'm the dedicated mt or solo tanking hard content. You're better off switching to Deliverance and just doing Fell Cleaves. Of course this only applies to HW content.
