All stam doesn't hurt you. But going dodge/dodge/def is a bit of a pre-3.0 strategy. For some experimentation, you might go str/str/def though. But if you are just moving into Sunwell, go stam. Those bosses will still hit you hard.
pre 3.02 I went dodge/dodge/def+stam due to sunwell raidiance. Now that it's gone, you can probably go str/str/def. Dependings on the rest of your gear, normally just fill it with stats you may be lacking. Stam is a safe bet
