It would kinda ruin the point of adventure
It would also be easy to get super rare items like sea lanterns as you can just warp to the location.
Not a good idea

 

-1 It's like x-ray, you've literally got everything with it. Ruins the fun.

I'd much rather adventure around, it's more fun and I feel more satisfied when I find the thing I'm looking for.

 

Here's the issue I see with this.

Based on a forum post from 2015, this is how /wild appears to work at the moment (if I recall it correctly):

Code:

Choose a random coordinate within the world limits and get the top block.
If the block is not on land, start over. (Unless you use /wild water [in which case it's vice versa] or /wild all.)
If the block is located in a town, start over.
If the block is not safe (e.g. lava), start over.
Teleport the player to this location.

Here's how this suggestion would work:

Code:

Choose a random coordinate within the world limits and get the top block.
If the block is not located in the required biome, start over.
If the block is located in a town, start over.
If the block is not safe (e.g. lava), start over.
Teleport the player to this location.

Now imagine the following situation: /wild mesa in a mining world that doesn't have a mesa within its 5000x5000 area, which is actually a pretty likely situation. Depending on how the code is written, the command execution will either run forever and eat server resources or it will be forcibly stopped via a StackOverflowError. It doesn't even require the complete absence if a biome; it could suffice to choose a rare biome.

Of course it's possible to avoid that, but I'm not exactly a fan of completely rewriting a command for a single feature.

As always, I'm basing my technical post on other technical posts I've seen on the forum before; I might have made mistakes or remembered something incorrectly.

 

/wild is dangerous to modify, as it's laggy when done a lot.
Something like this would 100% cause server lag as it's filtering the blocks based on yet another criteria.
