Best Explanation. Feral CC Broken Down.

-- Tappin
Not true. Ignoring trinket and external dispels (which everyone gets) we can be:
Feared: yes berserk can break and make us immune. That's 15 seconds of 180. Otherwise we're vulnerable to fear.
Cycloned: no way to break or be immune
Stunned: no way to break or be immune
Slept: this is uniquely feral. While we can shift out, it costs us time and dps. It's also not always possible to shift out or even see the cast.
Scare beast: see slept.
Rooted: yes we can break it, but it takes 1 GCD to break
Polymorph / Hex: yes, we can't have this cast while we're in form. It's still possible and we can no longer break it if it lands.

I'll give you that we're one of the hardest classes to CC. But you're exaggerating when "feral druids can't be CC'd". More importantly hard to CC doesn't automatically mean "overpowered in pvp". Our representation in arenas doesn't suggest we're overpowered even with so much freedom. Much more powerful classes in arena are not getting any significant nerfs.

Now let's look at the PTR.

Feared: no way to break or be immune
Cycloned: no way to break or be immune
Stunned: no way to break or be immune
Slept: same as before and still a uniquely feral vulnerability
Scare beast: see slept.
Rooted: no way to break or be immune
Polymorph / Hex: same as before, except that we'll get caught out of form more often because, while rooted our only productive offensive moves are:
a) bad heals
b) roots (not with cast time)
c) short range cyclone (far less often instant casts due to difficulty in getting combo points)

Most of us aren't against a few of the nerfs (bleeds, roots, fear immunity on a cooldown). But the root thing goes too far. On the ptr, can you name another spec that has no ways to either break or in some way be immune to at least a couple of these ccs: fear, cyclone, stun, sleep, root, poly, hex? Also remember that many other classes can still perform useful actions while rooted (heals, nukes, ranged interrupts, grip, etc). On the PTR root vs. a feral is almost as potent as a fear or poly. That's where they've gone too far. Ferals have gone from 'very hard to cc' to the most vulnerable spec.

The rest of your post is anectodal. If you want to talk about the change, look at how our abilities will match up to other classes after the patch and/or look at how the spec is doing as a whole. Individual duels or a single feral in a BG do not indicate an imbalance in the spec.
