Firstly...what does it mean that I have 16.53% Haste, but when I mouse hover it shows that I have 3,786 (8.91%)? What's the difference between those two numbers? Same goes for all stats when you mouse hover and get the numbers in parenthesis.
Secondly...since Haste is our best stat are we to absolutely stack it as high as possible right now with no regard to Crit or Mastery? If I reforge I lose a good chunk of Crit for a couple % gain in Haste. Is that always the better option? Or should we always aim for at least say...10%-12% Crit or something like that? Currently my Frostbolt is something like 1.72 second cast, so I assume stacking Haste as high as the sun is the best option for me regardless of how low my Crit / Mastery go in return correct?
Finally. I've read the sticky. I'm using the Icy Veins Glyph mostly because it looks and feels cool, and I assume sooner or later I'd hit that Haste cap to use it anyway, so there's no need to bring that up.
