Just a couple of things. I think taking maim away from ferals will be far too crippling. By taking away any kind of baseline stun you're basically forcing every feral into mighty bash. Typhoon and ursol's will never be taken and cyclone is still a shitty cc for ferals. Also mind you that since ferals had instant clone taken away their performance in arenas has been awful. Out of all the classes feral is one of the bottom classes for cc already. I know blizz wants to reduce cc but let's see how much cc classes like mages, rogues, locks and hunters are losing first. I know you listed the cc that feral will still have but clone and mighy bash are the only real CC left. Roots don't count as much and I'm not seeing your glyph of pounce mentioned anywhere in the OP so you might have accidentally removed it but without it feral would be seriously gimped.
Another issue I have is with your finishers. Currently there are 3 finishers Rip, Savage Roar and Ferocious Bite. Bite being the only direct damage finisher. You don't really want to tie rake application to it because overwriting a buffed rake with a weaker one simply cause you had to use your finisher will kill your dps. If you want to have an aoe finisher either make a new bleed or just turn trash into the finisher. You can even make bite do something like 50% of damage done is also done to all targets within 8 yards. Just don't tie multi target rake application to a single target finisher.

My bad about that double post on the last page.
Now, for AoE situations I think you absolutely have to avoid rake being auto applied as part of your single target rotation, especially if it's as a side effect of your aoe finisher. If I understand it correctly you want bite to be the aoe finisher? I can get on board with that idea but you still have to revert FTear back to FBite. I know I'm repeating myself here but auto application of a dot that's as strong as rake will do one of two things. A) you can't auto apply rake 100% of the time like hunters can serpent sting and you'll get horribly frustrated overwriting buffed rakes cause tear is your only direct damage finisher. B) you'll be able to keep it up by tearing 100% of the time and it'll be horribly op especially in pvp
