Again...I just really have a problem with you saying that a full mastery build can be a good way to play the class. The problem with a full mastery build is that unless you are getting more chi(read haste) than you would have otherwise you are going to take more damage, plain and simple. Your spikiness argument really isn't valid as it takes 1200 points to get 1% less upfront damage and if 1% spike is killing you you have other problems. Let's assume for a moment you were going to sink as many points as you could into mastery, you could maybe get another 6-8% off the top...but you would lose so much EB procs, possible loss of shuffle uptime, and your dps would go to shit meaning less raid guards. Kisho has said just a few posts back that mastery's real only niche is mitigating the effects of an under geared tank. I fully agree with that assessment. Even with the buffs next patch anyone who is not bleeding edge who is stacking mastery is most likely doing something wrong.
