Is There Any Way Of Improving This Suggestion?

I made a suggestion that got a nice amount of support, but half of them disagreed. I tried to read through the comments, but most of them weren't helping (i'm not saying that those who weren't helping are useless, i'm thankful for those that have at least commented). I tried to improve the idea and here is what i got.

My question is:
How to improve this suggestion?

----------

What is the mob?
It's a neutral mob that spawns after gathering a lot of nodes (it depends on chances and the level of material), when killed you'll receive professions XP and three tier 2 or one tier 3 materials. It's to make the players who grind for a long time a refresh from gathering even if it was a little bit (by clicking on a mob instead of a node :/) and a little bit of prize.

Information about the mob:
1. The mob won't spawn if there is already a mob that has spawned around 100 (?) blocks.
2. There are 44 kinds of this mob, each for its own level/material (Ex: Mob lv. 5 wood or mob Lv. 15 wheat).
3. Every material will have its unique design but the levels will only different on strength (you'll need to design only four mobs and the other ones will be the same version but with a buff)
4. The mob won't need to necessarily be strong.

How does it exactly spawns?
The chances to spawn the mob raises every time you gather a node (the same node) and when it spawns it will reset the chances. The chances will stay zero if there is already a mob 100 blocks from the node you gathered.
Here's an example

Spoiler: The chances for every material level

1. Materials level 1,10 every time you gather a node the chances to spawn the mob will rise by 0.1482% until it gets to 20% which means you’ll need to use tools 135 times to get 20% chance to spawn the mob (If you got 45 weight limits you can gather 135 materials with three loops of going forth and back to the bank/refinery).
2. Materials level 20,30 every time you gather a node the chances to spawn the mob will rise by 0.1588% until it gets to 20% which means you’ll need to use tools 126 times to get 20% chance to spawn the mob (If you got 85 weight limit you can gather 126 materials with three loops of going forth and back to the bank/refinery).
   
3. Materials level 40,50 every time you gather a node the chances to spawn the mob rise by 0.122% until it gets to 15% which means you’ll need to use tools 123 times to get 15% chance to spawn the mob (If you got 125 weight limit you can gather 123 materials with three loops of going forth and back to the bank/refinery).
   
4. Materials level 60,70 every time you gather a node the chances to spawn the mob will rise by 0.122% until it gets to 15% which means you’ll need to use tools 123 times to get 15% chance to spawn the mob (If you got 165 weight limit you can gather 123 materials with three loops of going forth and back to the bank/refinery).
   
5. Materials level 80,90 every time you gather a node the chances to spawn the mob will rise by 0.0814% until it gets to 10% which means you’ll need to use tools 123 times to get 10% chance to spawn the mob (If you got 205 weight limit you can gather 123 materials with three loops of going forth and back to the bank/refinery).
   
6. Materials level 100,110 every time you gather a node the chances to spawn the mob will rise by 0.0834% until it gets to 10% which means you’ll need to use tools 120 times to get 10% chance to spawn the mob (If you got 245 weight limit you can gather 120 materials with three loops of going forth and back to the bank/refinery).

Summary for the example: When you gather nodes the mob has a ?% chance of spawning and it will rise every time you gather a specific node for it to spawn until it reaches the ?% that it was decided for.

I don't think i changed anything.... so anyone has any ideas?

Note: Even if it was something like "Write the chances for spawning the mob" is alright, there is no need to write a bunch of text.

 

It sounds cool, but I'm not sure if the mob spawning system can increase chances based on nodes gathered. It would take additional coding to make the mob idea work, which may not be top priority for the devs at the moment. Plus, I feel that people might want to separate gathering from fighting, though most locations force you to fight off mobs anyways so I'm not sure why that would be a complaint.

There's also the issue of how this will affect the economy, and those who thrive off selling high tier materials might not like this idea because it will reduce the rarity and therefore value of these items. Most suggestions are like this, and you aren't going to get full support for it because everyone has their own opinions about what you suggested. I'd say just leave your suggestion as is, and if an argument comes up try to use it to create a counterargument on how their opinion can be integrated into your idea.
