I would like to give me input to this thread even though I'm not the best warrior. I learn alot from most of you from the maths and general input that you give to these posts, and I genuinly appriciate the work you people put in. I don't do simcraft myself and don't really understand the math of it all(would like to learn in the future) though, so when I thought about this whole haste issue I was thinking really simple and comparing it to my ret paladin.

At the moment, with my mastery, I get between 19-20% increased damage when I'm enraged. If you put that into perspective of a ret paladin that has a 20% increased damage done on a 2 minute cooldown it just looks so obvious to me that mastery is the best way to go. We can have like 70%+ uptime on what is effectively paladin wings. In that sense, to me, mastery was the best way to go. I then read the math that people had posted and that backed it up.
My point is to get the most accurate answer you have to use maths or read posts from theorycraftersr. But you can also think about it yourself and it doesn't nesesarily have to be that complicated, atleast in this case.
Just my two cents.
Edit: Don't get the misconception that I use bladestorm on every fight please
