Priority should be given to addressing the most essential features and fixes, rather than introducing "new elements" that end up being plagued by long-standing issues... again!
1.) Light and Light Sources Overhaul
First, it's imperative to FIX the Brightness issue/cheat! (which has been a long-standing problem for 8+ years now.)
This issue can and will be exploited for an unfair advantage.
For instance, the current Brightness settings render Night Vision Goggles, Weapon Lights, and Helmet Lights entirely ineffective up to completely useless.
Another concern is the way Light and Light Sources interacts with Solid Blocks...
Daylight can penetrate deep into caves, reaching depths of 30, 40 or even 100 blocks?!
Ideally, Daylight and other Light Sources should not even pass through ONE Solid Block!
2.) Revamping and Expanding Farming Mechanics
The current System of using Fist and/or Knife attacks to harvest plants is inefficient, slow, and just unsatisfying at all.
It's perplexing why there isn't a designated "Tool" for harvesting?!
Implementing such a tool shouldn't be that hard and complex task, especially considering the numerous Unity games that have already incorporated similar features.
Specifically, these two features are of paramount importance and have been recognized as long-standing known issues.
It is crucial that they are addressed BEFORE introducing new "potential" long-standing problems!
You don't think so?
