Unbound Changeling trinket gives wrong secondary stat

The Unbound Changeling trinket has a chance to give you a variety of different secondary stat bonuses - Crit, Haste, or Mastery - depending on what Well Fed buff you currently have. If you use a food buff that gives you Mastery, for example, you'll have a higher chance of getting the Mastery food buff. The same is true for Haste and Crit. There is also a small chance that, regardless of the food you eat, you may get a buff for all 3 of these secondary stats. This stat IS intended to change when you eat and you are not guaranteed to get the secondary stat that you want.
