As I've seen some people post here, the Bane plus aerial slash. I however do the same for each pet, pairing the pet's AOE with Bane. I just label them as Garuda Bane, Ifrit Bane, Titan Bane.
I think the other macros I use have been mentioned. Swiftcase/Shadowflare, Swiftcase/Resurrection. Eye for Eye/Virus

I have a macro for when you Summon your pet that puts it on Obey once summoned. I use this because I prefer my pet on obey, I know some people don't care either way. Here it is anyways.

/macroicon "Summon"
/recast "Surecast"
/recast "Swiftcast"
/ac "Surecast"
/wait
/ac "Swiftcast"
/wait
/pac "Obey"
/wait 6
/pac "Obey"
