The additional recipe ranks can be obtained either by exploring the outdoor Broken Isles zones or as rewards when you dive into the dungeons of the region. If you’re feeling up to the challenge, you can aim to hit skill level 100 and player level 100 to open up profession world quests, which rewards higher rank recipes for your Legion gold making operation.
Inscription and darkmoon decks remain highly profitable still as long as you approach it with the right mindset and understand that it is a commodity market and the goal is not necessary to sell crafted decks. For me, it's an exercise in managing purchasing Linen & Herbs below market, balancing opportunity cost of converting linen to expulsom, and mass purchasing underpriced individual cards and relisting them at a profit but under the crafting cost so that they move. That's the primary goal, and you naturally complete decks that you sell but you don't go out of your way for.
Patience and extra gold are rather important for the mounts so it might not be best for you right now. As for the operation (Wrath and Pandaria mounts right now), you need a miner (ore is cheaper than bars), transmutation master alchemists (living steel and some time eternals for daily cooldown, titanium and riddle of steel), and potentially multiple engineers (for more Sky Golems, plus at least one gnomish and one goblin if you want to do both rockets). The best way to source Pandaria mats cheaply is to buy up Spirit of Harmony when it's cheap and check often for mats cheaper than the conversion rate (1 Spirit buys 20 ghost iron ore, 5 trillium ore, 20 Kyparite, and more). Same with Eternals (for crafting titansteel)...you have to regularly check and grab them up whenever they're cheap (frozen orbs can be exchanged for eternals in old Dalaran too so watch for some cheap orbs as well). I also sell Golden Lotus on the side since it goes for more than the Spirit cost. (Edit: Also should point out that at the end of the expansion everyone is bored with nothing better to do so the profits on the mounts have dipped to as low as 5k.)
They already are with the leveling changes and Blizz fucking up the API. AH focused players have been flying blind the last few weeks without API, as well as the re-introduction of unobtainable items that are now back in the game, as well as the enchanting changes (Dusts got squished already). Some of them are waiting it out, others are just doing their normal thing.

The older brother of this potion originally came about in Cataclysm as the Potion of Treasure Finding, and is actually one of the best ways to make money. Since most Pandaria mats are constantly farmed, they usually sell for less than the Cataclysm mats. This makes using this form of the potion more effective for making gold. Not to mention that creatures die faster to level 90s since they were made for the previous expansion, making farming the treasure chests that drop rather easy.

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.
