Hey there peeps

I've been thinking about the 5.2 patch with haste vs mastery and the 4set.
Would you say that haste, EM, PE is better until 4set and then go back to mastery EoE and EB as I have now in 5.1.
Haven't really read in the ptr thread as it is 106 pages long and talk about all speccs which I personally don't have
time to read through.
