I think that where you have those 6 boxes that show what you have equiped there should be a list of what your Weapon Attack, Defence and Attack Speed are, right now there is no possible way to tell how much defence you have unless you check on the forums, I think that this is an unnecessary inconvinience, not to mention waste of time.
An example of what I'm saying is like this
[] O [] Attack: 34
[] U [] Defence: 15
[] /\[] Attack Speed: 140%
this is kinda pointless
