WowHead reported that the 8.1.5 patch in the Public Test Realm added "Stanley", a thin man with gray-white hair and sunglasses who greets people by shouting “Excelsior!” So far, he was only found in Stormwind, reflecting the colors and armor of the Alliance. But a little more in-depth understanding of this update also has two Stanley character models: one is a neutral colors without armor, and the other is wearing Horde gear.
There's a few profession crafted pets in BfA on the horizon - Battle for Azeroth Tailoring is getting a Hot Air Balloon style pet, and BfA Alchemy looks to be getting a brand new Transmute Meat to Pet. There are some mount buff consumables from both BfA Leatherworking in the form of a mount barding, and Blacksmithing in Battle for Azeroth will be able to craft Stirrups and Hoofplates to increase mount speed and allow you to interact with things while mounted.
I know if you aren't using hunters than you'll really want the loot-a-rang for easy looting, so that would take up one of your professions. In all honesty If i was going to do it id level up a hunter team and only hyperfarm with them, while doing other things with the mains. As far as regular professions go, they don't really seem worth it anymore like they did back in the old days, so I'd personally stick with gathering stuff as you are hitting nodes x5
I'm aware that the LS chain can be xmuted up all the way up from GIO. This is great since it means ultimately you only need to track/acquire one item. The procs can certainly increase your profit margin, but as I said in my top-level comment the profitability of the whole endeavor is server-dependent. These numbers will of course vary from server to server, and for some it might be worth it.

All of my gold came from everyone buying stuff at a really marked up price for instance BS 2h mace if it proced epic i was making at least 125k per one and i was making batchs of 10 to 15 it was like 25k for blue and 125k+ for epics at the time. And i was buying the ore for like 16g to 40g a pop so huge profit. Im still trying to figure out what im gunna do now to rebuild it will be a slow process now.
