A lot of thought and consideration has been going into how exp would work and be gained, so I thought I would give my two cents.
A new type of crafting table would be added called a research table. If the players place an item on the table it will be “analyzed,” which destroys the object and gives the player exp based on item rarity.
This table would also allow players to craft things such as syringes, notepads, and other similar instruments. These items can be used to collect exp outside of the base. If you fill a syringe with zombie goo and take it back to the research table you would receive a large boost to exp. Notepads could be used on objects such as scorpion seven notes to get boosts as well.
Other buildings could also be added such as a weather station which generates exp based on windiness /rain!
The main purpose of this change would be making base building more important and make grinding exp more than just mowing down zombies and trees. This combined with books that give exp could greatly enhance the system.
If Nelson does decide to change the exp system to make it so you level up at something by doing it, then the research table could give “universal” exp that can be put into any skill, which would help people who hate mindless grinding gain skills in a more interesting way.
Thanks for reading!
