For example, without using EB/FoF that often (when we balanced stats for RoRO), the haste needed to not be energy starved was roughly 9-9.5k. Not balancing our stats (now for example) it takes most "good" WW's about 6-7k haste using FoF/EB practically on CD. That's another 2-3k stats we can push into mastery/crit, or move our gems from yellow to maximize secondaries to red/orange for agi. With this trinket I've found I can drop my haste another 1.5-2k because of the increase in EB/FoF. That's a 4-5k difference in haste that can be added to crit/mastery. Which is huge.
IMO this is our BiS trinket, comparable only to Harrom's.
