My Dps priority will stay the same in 5.2, because I'll be using EotE/UF. It just feels right combo for Enhancement.
PE in my opinion is horrible; boost to to FeT/EeT dmg and new skins for both. On a 5min cd.... lame as f*ck.
EB isn't that bad at all, it is my off spc talent of choice. When the lvl 90 talents were introduced I was kinda disappointed... Back then UF was only talent that I liked, and I still love it. Even tho it's "passive", it just flavors the rotation.
