"Even after we fixed their mastery, Feral druid bleeds still do a lot of damage and are undispellable. We plan to shift some of that damage back to main attacks. They are also a little too hard to control. Given that they are already hard to root, snare, or polymorph, we think the fear immunity from Berserk is too much."
Fair nurfs in my opinion.
My only concern is I hope this won't spill over into pve.
