That's what it's looking like on the patch notes. FFS, Blizz is really peeving me off by screwing with my gameplay during the middle of an expansion. They did the same thing with Devastator and removing FR from Prot.
Yes the Arms FR playstyle was retarded from the ground up and should have never been implemented....but it's there, it took me sometime to master it and actually enjoy it, and now they gut it. All we wanted was some freaking reliable AoE and the ability to swap targets. >.<
