[Rejected]Villager trade tweaks (enchanted books)

So I've mentioned my problems with book trades plenty of times in game, but now that I have a way to modify them, I figure it's time for a discussion thread.

For clarity in this post, "cost" refers to the trade price in emeralds. "Value" refers to player perception of how good an enchant is.

Source for trade costs

Motivation

The cost of a book is based entirely on its enchantment level. This leads to enchants like infinity (min cost 5) being less costly than less valuable enchants like efficiency 3 (min cost 11). Also, while each enchantment level is at least twice as valuable as the previous level, the cost only grows by a minimum of 3.
I believe that changing enchantment costs to match their value will create a better experience when trading with villagers and setting up shops.​

Goals

The value of max level enchantments will be determined by player input (in a poll, in game, or using shop prices if need be). Because this is relative, the values will be scaled to a reasonable number of emeralds.
The value of lower levels will be halved, rounding down, capped at 1. For instance, if sharp 5 was valued at 16, sharp 4 would be valued at 8.​

So that's my idea. This thread is for deciding if it's something we want to do on ShadeCrest, or if I need to tweak it in some way. If it gets enough support, I'll make some kind of poll to determine enchantment values and post it here.

 

Treasure enchants are ones you can't get from normal enchanting. Currently that is mending, frost walker, curse of binding, and curse of vanishing.
Unless I'm getting player feedback, all of those things just help guess the value. I don't mind that, some people would just not like it very much.

Thanks for the feedback!

 

Thought about it more, and I can't use a survey to determine value without a TON of data. I will need to make some metric to judge values.

 

Finished the plugin, it will be on the server on the next restart.

The base cost is 32 emeralds. Each level below max cuts that cost in half.
Treasure enchants (mending, frost walker) have a base cost of 64, curses have a base cost of 4.

The base cost can be modified by config.
All enchantments can be individually modified by config.
The plugin itself can be enabled/disabled by config.
The config can be reloaded at any time to apply changes.
No villager is permanently modified. If the plugin is removed, all trades return to default.

I'd say that's a success. If the values seem unfair, we'll just change them on the fly until we get something that works.

 

I posted what I set costs to, they were at 60 due to a bug.
