New Multiboxer! Looking for class input.

[Ualaa]

My Ferals (in Cataclysm) used a simple macro:

#show
/castsequence reset=target Mangle(Cat Form), Rake(Cat Form), Mangle(Cat Form), Mangle(Cat Form), Rip(Cat Form)

Until you get Rip, you'd use the Ferocious Bite.
Pretty easy, one button mash.
Along with sending IWT.

In MoP, you'd want to modify your rotation to always have Savage Roar up, when killing something that will be there for a while.
When questing, the initial Mangle x5 would drop just about everything.
Also the four non-finishing moves, prior to the finisher, would almost always kill anything so the rotation was less important.
However, testing on a target dummy... four moves, with one combo point per move and two on a crit, is almost always five combo points before the finisher.

Druids had (and have) a 20% chance per combo point, for their next Nature spell (of under 10 seconds, base cast time) being instant cast after using a finishing move.
You'll either have four combo points or five, with the above rotation.
With a 30% crit rate, which isn't all that high, you have better than a 95% chance of having the instant cast.
The issue mainly is, almost nothing is still alive after five moves from five druids.

You can glyph Savage Roar, such that it can be used without Combo Points for a 12 second duration.
I'm not sure if that's a DPS loss, compared to a different major glyph, as one of your three...
But that certainly simplifies the rotation... amend it to: Mangle > Rake > Mangle > Mangle > Rip > Savage Roar.
Again, not sure if that's optimal, but most of the time... if things are dead before you reach the fifth move, then you don't need it...
But it is automated, as in will go off without your needing to concentrate on using it... just DPS away (the five move rotation, is close to every 10 seconds... and 0 Combo Points is a 12 second duration).
You could experiment, and move Savage Roar to the initial position (before the first Mangle).

Nature's Swiftness, every minute on each Druid (without dropping DPS Form), certainly increases the effectiveness of the composition whether Feral or Balance.
With five Druids, that is five Healing Touches every minute (approximately every 12 seconds).
With ten Druids, that is ten Healing Touches every minute (approximately every 6 seconds).
If you need Healing, Glyph of Cat Form increases heals received (while in Cat Form), by 20%.

I like both Feline Swiftness and Displacer Beast.
Feline Swiftness increases Cat Form from 25% to 40% increased movement, all the time.
Displacer Beast, is essentially Vanish... allowing you to pick and choose your battles even more so.

Incarnation, allows the use of Stealth abilities without Stealth.
And removes the positional requirements on Ravage, meaning Ravage without Stealth and from any direction.
Incarnation is 30 seconds, every 3 minutes.

Welcome to the community

While you have RAF, level lots and lots.
It's relatively fast and a lot less painful now, then it will be to add another set of toons down the road, when the RAF is gone.

Ualaa cried when his raf ran out. I remember it well...

Ualaa, thanks for the feral druid knowledge! I've never played feral spec, only balance, so that is extremely helpful! While I have the RaF I plan on taking every class to 80!

I still haven't started boxing yet but it should be happening by the end of the weekend.

Dont wear yourself out though...make sure you stop and rest...leveling everything to 80 has been the bain of all multiboxers, and in turn has lead to burn out.
