Feral doesn't have a steep curve.. You no longer need to powershift to heal or cc. Bleeds are terrible so dot swapping is also no longer a thing. Literally all you do is cyclone a healer and explode a dps. Press all cooldowns and party with an enhance shaman or rogue. In 3's can play almost any comp just because of your burst. After burst is done you basically just run and cc for 3 minutes and do it again.
Pretty much guarantee that feral cds will be cut in half. half the duration + half the cooldown. At which point people can go back to "chain cc that feral before he murders you" and feral will go back to being pretty bad. And/or finally being back to a "steep curve".
TL:DR : Bring back Feral bleeds and reduce their burst damage. Pressing Incarnation + Nature's Vigil and Ravage + FB spamming isn't fun.
