I'm a bit of a slave to the reforge/gemming/enchanting advice of askmrrobot.com - I'm way too lazy to do the math on my own for each toon. =)
I'll have to post on their forums about the mastery thing for 4pc.
I wasn't aware of the glyph thing. I'll have to change that out.
Thanks.
Edit - Turns out they (AMR) are aware of the haste/mastery thing, but they are unwilling/unable to setup AMR to detect for 2pc/4pc bonuses to alter stat weights, so their advice is to manually adjust stat weights.
Any suggestions on what my stat weights should be?
