Is It Time For MD?

After getting sorcerer today and seeing that my mystic is my second strongest class, i thought it might be time to invest in MD.
Current masteries:



I only have 57 mastery points as i have not explored Act 4.2/3. In working on it, although those points are probably going to be for Resonate.
This is my desired setup:

Removing all Glass Cannon, a point from courage, and reducing assasins to 1. As well as Removing 1 from salve.
So is 3/5 MD enough? I have just short of a million loyalty so this change should be easy-ish.
If it isnt enough, then ill use an Act 4 point to raise it to 4 or ill do 4/5 DW.
Thoughts?

I have 3/5, that's the sweet spot. You don't want too much power either.
The bump to 4/5 was noticeable, but mainly for SymSupreme. 3/5 should be fine.
3 or 4 points in MD mostly depends on how often you use mystics and which mystics you use. I absolutely loathe using Sym with anything under 4. Most other mystics can operate just fine with 3 in most situations.
