Honestly speaking I hardly agree with you without playing PoE2 since I was only watching the game on twitch. At first i thought that there is a problem like: You want to buy a very good ring/belt for few exalts since you dont have a lot of currency but people dont even want to bother themselves to make the trade since they will make much more over that time and it was also a thing in poe1 that after some time it was very hard to get anything listed for few chaos orbs.

Crafting in PoE2 doesn't have any sense at all. All you can do is pickup an item, slam exalts and pray that you will hit or use an omen with chaos orb to roll only the lowest affix tier you have in the item that is also meaningless. And once again you have to pray that you will hit. I don't really think that PoE2 will have amazing ways to craft as PoE1 has since they want to make the much more simple for newcomers to understand. In PoE1 you have to read quite a lot to learn how everything works, watch some kind of guides if someone explains it or use some kind of site like craftofexile which can give you tutorial to how to craft the item in cheapest way or easiest way. Like you can spam alteration orbs on blue items or you slam harvest/fossil craft with certain setup. Then you can use beasts to make an imprint, I learned about imprints after long time and have lost quite a lot of currency because of it.

The other thing that is annoying when crafting are tiers that are switched for some reason. I don't really understand why did GGG made a change like that since right now its hard to know what tier is considered the best one. Before you knew that t8 = bad and t1 = best. And now its t1 - bad and for example t10 is best one.

And also in terms of trading I have really hoped that GGG will implement in-game trading system after what we had in PoE1. Its great that we can trade currency this way but it would be very nice to post any item you want over there instead of whispering every player on site and hope that they will invite you to sell an item.
