There's no grind. Well, there's sort of a grind. They made it so that after you've run your 2 daily chaos dungeons you can keep running it, with like 1% drop rate for the normal shit, and you'll also get a new currency drop that you can buy shit from a vendor. It's really slow, but I guess it's something to do if you really like the combat. It's faceroll easy though, you barely have to look at the screen. I assume NA will have it in their version.
There are gathering skills, that you level up and get certain bonuses/abilities. Hard to tell what the economy is going to look like in this frankenstein version, but I recommend fishing. It's the only way to get the mats need to craft a material needed for gear upgrades, so it will be hella profitable at tier 3 (Punika) You don't technically craft yourself, you go to your estate and queue up crafts in the menu. Everyone has access to everything, but you have to "research" things that open up as you level your estate. Research costs basic wood and ore, so initially that will prolly be worth gathering too. It should remain somewhat decent (and ore becomes fastest to blow your labor on once you achieve a certain skill) because you constantly need them for research and to repair your estate ships that you send on missions for mats and shit. I can't compare wood and ore prices to RU anymore, because they recently changed some shit and tanked the prices on those like 90% and its still recovering. Early on crafting potions will probably be somewhat profitable, another one that's hard to tell in RU, due to recent changes, plus the fact that login/event rewards flood the server with bound potions. (another retarded thing.)
Also crafting costs gold. Lots of gold. If you check prices, you can sometimes make a profit still by buying stuff off the AH and crafting it, but your profit will only come from "extra" crafts that has a low % chance to proc. Like, the upgrade mat, I can craft 30 at a time, 10x30 per slot. Each proc is an extra 30. Every proc is pure profit.
The amount of items you can craft is limited by your crafting slots, and your estate "energy." You can research more slots as you level up, and the monthly "blessing" opens an extra 1 too. Same for research.
Always make sure to spend as much energy as you can every day, so your estate keeps leveling.
Sorry this is so messy and rambling. It's hard to explain shit with so many systems stacked on top of each other.
