And then when you actually want to do some crafting and then want to buy crafting components in bigger numbers.. good luck LOL
Achieved with a single press of a button? There's a bulk sale option in your stash (and on the website) in case you never bothered to look before crying. Somehow I have zero problems with buying tens of stacks of currency to reroll orbs or selling essences 50 at a time that make mad bank. I think you'd be surprised to hear that I've been selling "crafting components" for divs as my primary income along with logbooks this league, and I got all voidstones along with the perfect solved build and stopped playing because I pretty much completed the game with a chest full of divs that won't even buy me anything I need at that point. Like less than halfway into the league. I didn't need any luck.
You do but it is in all kinds of currency that you then need to trade for useful currency using same trade system.
There exists a little something called a loot filter, it lets you filter all the shit you don't need or shouldn't bother with. So you can spec your atlas into something you want to farm and pick up just that and sell it. I know, it's that easy.
Before I switched to SSF I spent as much time wasting time checking values of different items, putting them on sale
Sounds like a you problem. If you played the game for five years as you claim (I find it hard to believe considering what you're saying) you can tell whether an item is worth selling just having a glance at the modifiers and the item type. If you're hauling twenty items a run to meticulously price check and sell for 15c a pop, I have bad news for you: you're doing it wrong. Watch a guide on youtube, people make pretty good ones about what you should be aiming to farm and profit from. Also, trade is an essential part of the game, it's not "time wasted". That's why SSF is it's own separate league. You sell to get profit, you buy what you need. The entire end-game is built around farming and selling. It's not going to be completely streamlined for you with a press of a single button, it's a barter market that you need to engage in and know what you're doing. In other MMO games with automated markets in order to make a profit it is still required for you to know what you're selling and why, to know it's market value and do research and comparison. Don't want that -- play SSF, but there's no reason to whine because of user error. There's tons of information out there for years to help you out, even with complete spoonfed formulas of how to spec your loot, what to get, what to do and how to sell. If you're spending hours price checking each item worrying about whether you can get profit in the margin of 5-10c no wonder you feel miserable. And if you were selling items that actually go for something, then that margin wouldn't be an issue in the first place, and by extension, the problem that you described wouldn't exist.
Also, pretty much all end-game strats I know are focused on bulk selling currency or mechanic based stuff. You don't "farm" weapons or gear for sale. It's an outlier where something super good drops so you just pick it up to throw it in a sale tab because why not, it's income. Or, people hand crafting gear specific to a popular build and pushing it on the market for like 4-15div. The only people who sell the low-c items they pick up off the floor and price check for some reason are new to the game and abandon that behavior very soon.
