So far, the other thread just is totally chaotic, so i start a new one specific for 5.2 Enhancement.
With the new simcraft, we get following results. I'm using the BIS profile becuase it is a realistic itemlevel at the beginning of 5.2 and few weeks after.
Every sim is done 10000 times.
EotE + UF: 122825
EM + UF: 122300
EM + PE: 118270
EotE + PE: 118265
EotE + EB: 116946
EM + EB: 116943
As everyone can see, UF totally dominates, EB is no choice at all.
Now the PTR version (same fight length and so on):
EM + PE: 124818 (+ 5.5%)
EM + UF: 124553 (+ 1.8%)
AS + UF: 122514
AS + PE: 122065
EotE + UF: 121918 (- 0.8%)
EotE + PE: 121352 (+ 2.6%)
EM + EB: 121292 (+ 3.7%)
AS + EB: 118592
EotE + EB: 118420 (+ 1.2%)
As everyone can see, in it's current state, EM totally takes over, making EM + PE the best dps talent, but pretty close.
EB just stays no real choice. It will be not worth taking.
You may switch PE and UF, depending on fight. EotE might be best for AOE fights.
I still expect a EM nerf coming. The moment they nerf EM, UF will be again a little better.
