The barter system as it is right now is a quite good one. It allows for players who are unable to be active enough to grind, but still at their computers over several hours to still make money. However there are some issues, notably with randomness (like many other tings in this game) that prevent full enjoyment. Currently, when bartering land materials for Teir 1, you get a single white item for your group of materials, and you can make 6 trades. Bartering Teir 3 and 4 mats for 4 and 5 mats is similar, they are always 6 trades of 1 T3 for 2 T4s, and 4 trades of 1 T4 for 1 T5. However bartering T1 mats for T2 is 2 trades of 1-3 materials, and T2 for T3 is the same issue. Having random trades for the materials is problematic because which materials are chosen each referesh is random. You could find yourself ina  situation where the material you need is only a 1 to 1 trade, and you didnt have a chance to build up a stock of materials because it is shown to you so rarely. While people who have been doing this for quite some time do not have that much of a problem with this situation, it greatly increases the struggle of people new to bartering from getting started, and inhibits the growth of people who have started recently.

In general, the two layers of randomness hurt people who are jsut getting started and thereofre making very little money anyway, and make it more difficult to get to the point where you actually make reasonable amounts of money as well. I propose that instead, those two trades are always 1 material for 2 of the higher ones. This provides a consistent way to grow regardless of which materials are offered.

This is a good suggestion imho.

I personally like that you can have x3 barters, and I didn't feel like focusing on the x2 and x3 was that hard when I was starting out, since having 6 trades at tier 0 and only 2 at tier 1 means you'll stock up items.

But if you feel that it would be helpful for newer barterers, how about they are always x2 when you have 500 barters or less, and after that they behave like they do now?

I like the 3x trades as an option, I don't even bother with 2x It feels like a waste to do those.

Yea, having it x1 to x3 is still better. If you're at a stage where you don't have a good stock of t1 to t3s, then your focus should've been somewhere else rather than tiering up. It does suck when you're low routes and you hit a 1:1, but in the long run you'll like being able to get x3s much more than it being stuck at x2.
