That's a really cool list! I'll avoid quoting what you wrote to avoid quotebombing the thread so if someone's reading this on Page 3, you'll have to back-track to P1 to get the gist of it.
Anyway, here goes.
Maim and AoE issues
I really like the idea of having an AoE finisher to augment our rotational cycle based on the number of targets. I don't think it's solving one of the main issues with target-swapping though:
Losing CPs when you generate CPs on a new target. I was brainstorming of something like Touch of Karma or Kil'jaeden's Cunning in the sense that you toggle an ability on a MARK (with perhaps a toggle cooldown) and then whenever you generate CPs on another target, you would keep the CPs on your original MARK (but you would still lose them when switching to a non-MARKed target). This would come in handy to alleviate some of the pain associated with swapping off of your main target (boss, etc.) to help out killing/bursting something else really fast and then continue your cycle on the boss without incurring a dreadful 5-15second cycle reset (especially if the off-target appears at such a time that you do not or cannot have Berserk/TF available).
Of course this is all under the assumption that it will still be preferred to keep near-100% uptime on Roar and Rip in WoD.
AoE issues contd.
I don't know about you but I have a grudge with our two main aoe spells (high-volume aoe, nevermind rake spam):
1. Combo Point generation on Swipe is RIDICULOUSLY unintuitive (not to mention it doesn't benefit from Primal Fury).
2. As long as Thrash remains a single-target component of our rotation I find it dreadful having to overwrite a strong Thrash snapshot on the boss with a weaker one just because I'm trying to hit a couple lepper gnomes on the side (while snapshotting is out for gear, we can still snapshot damage modifiers).
OoC and Ravage/fillers
I think Aggixx already raised really good issues with this especially in regards to pvp but by far the main issue I see with this is the introduction of yet another flat-damage CP generator. I'd be more leaned towards a blackout kick-esque (windwalker monk) damage debuff but I don't think either extreme is too enjoyable (or scalable). Maybe there's a sweet spot the developers will find.
Bearcatting v2
I really like your idea with Lacerate (feral). I've long been a fan of mixing in bear form into our dps rotation ever since Windlord in Heart of Fear and I think our two feral forms suffer from a lot of Vanilla baggage by not sharing certain spells cross-form (or even cross-spec). Mangle barely got fixed (no pun intended) last expansion but it's still two (three, actually) different spell IDs and icons. I'd love to see some overlap of Bear-oriented rake usage (in bear form of course) and some lacerate stacking in cat form perhaps replacing faerie fire or substituting an identical bleed as thrash but not overwritable by AoE.
