Haven't really finalized macros yet (slowly leveling other teams to 75th for Cataclysm Alchemy).
But this is what I've got so far.

A basic choice will be whether you want to bother with getting/staying behind your opponent.
With a single toon, you can probably joust and jump through them and spin for backstabs.
Not sure if you'll be able to keep multiple ferals behind your target, even with IWT spam.

Shred based macros will be more damage then Mangle based, if you can stay behind the target.
But if you hit Shred, when you're not behind the target, nothing happens.
And unfortunately, we cannot go with:

#show
/cast Mangle
/cast Shred

If you could write a castsequence macro, with two lines similar to the click replacement... and have /cast Shred as the second line, with a castsequence as the main line, that would be ideal. Shred whenever it is available, but Mangle most of the time.

So far, I've decided since I'm playing 5x the same (Feral Cats), to go with individual buttons. I could probably replicate a click castsequence with creative usage of Steps, but don't want to duplicate (via boxing software) a feature Blizzard has chosen to remove.

So, I want to be able to spam a move like Rake, without it recasting for a druid who has successfully Raked.
This format should work fine:

#show Rake
/castsequence reset=3 Rake,Null

I have a Feral Charge (Cat) > Ravage macro. Looking at PvE openers, many suggest Charge > Mangle > Rake > Ravage, but I'd think a straight Charge > Ravage will be better for PvP, as we're not guaranteed the targets back for any prolonged time.

We basically follow a priority system (not sure the relative order) for DPS.
a) keep Savage Roar up.
b) keep the Mangle bleed up.
c) keep the Rake dot up.
d) keep the Rip dot up.
e) Shred/Mangle for combo points.
f) Ferocious Bite, when we won't clip Rake/Rip/Roar/Mangle.

We have Tiger's Fury, for extra energy/burst.
Berserk has a similar use, unless you want to save it for immunity to CC some effects, in addition to the trinket.

The group/raid Dash like skill, on round-robin, will be excellent for running/intercepting flags in the middle of the field.



I'm leaning towards glyphing:
Prime - Berserk, Mangle, Savage Roar.
Major - Entangling Roots, Rebirth, Thorns.
Minor - Aquatic Form, Dash, Unburdened Rebirth.

Berserk is not the optimal choice for DPS, but it gives 5 extra seconds of fear immunity -- which is one of the largest weaknesses of a boxed team; 20 seconds instead of 15.

Rebirth seems to be on a shared cooldown in a raid/party, if that's the case for battlegrounds as well... then it will not be an optimal choice for all of the toons, although it will be a strong choice for at least one toon -- having an ally back at full health is fairly strong. I had envisioned five Battle Rez's, on round-robin, brining my toons back at 100% health.

I really like Entangling Roots, as an instant cast. Roots and Cyclone are both useful control options.

From what I've seen, thorns is really nasty against Melee. Glyphed, we can have it up most of the time. Only thing that sucks, is it drops us out of Cat Form to apply it.

Nature spells with cast times under 10 seconds become instant cast, with 5 point finishing moves. Tracking the CP's on other toons will be fairly important. Battle Rez, Cyclone and our Healing spells are all eligible for this. Thorns and Entangling Roots (glyphed) are already instant cast.
