what trinkets do you have now? and you use glyph of regerative magic and glyph of the loud horn?
Got normal 4/4 Eye of Galakras and 4/4 Raid finder Thok's Tail Tip (Normal Fusion Fire Core can suck my dick), and yes on both glyphs.

I use the 1h Axe Malkorok drops and a warforged Paragons Sword as Frost DW.
That just comes down to your preference of talents and haste levels then. Someone else with your exact gear could take PL and have slightly higher haste and never have a free global. Someone could also take a little less and slow things down a bit more. We set our haste where we feel comfortable based upon our approach to fights, so if it's at a good point on med-high AMS soaking fights it's prob not enough on fights without a bunch of it.
I mean for example I can feel a big difference in rotation on Nazgrim compared to Garrosh because one has super low AMS soaking and the other has high AMS soaking.
AMS soaking isn't worth much in 6.0. It's still worth doing, definitely. But it isn't game-changing like in live today.
