I totally agree Int>spirit>haste>mastery>crit in that order. But.......
http://elitistjerks.com/f73/t110354-resto_cataclysm_release/I believe if you read the last few pages of this thread you will see that slourette has done some number crunching and came to very similar conclusions I have. Once you reach the break point in haste - Mastery becomes the better stat especially in longer fights. As our gear gets better and we can reach the next break point (2K+) Then by all means we will need to get enough haste to reach that point. Until that point stacking haste will not give us a tangible benefit like it did in Wrath.
Using Hamlet's spreadsheet as my guide and plugging in my gear at this time. My throughput actually drops when I substitute additional haste for Mastery providing I stay above the 1423 haste break point.
There are several unanswered questions about Druid mechanics but we are getting off of your original topic. I would love to take this discussion farther maybe in the class forum.
