1. Better loot drops/ enemy types & variety of enemies. (eg Fenrings only drop a fang)

2. More uses for older materials, specifically for building & crafting - Ancient Bark could be mossy roofs for example.

3. One of my biggest annoyances: Workbench upgrades for early game. For Deer Leather & Troll Leather armour to be fully maxed out you need to have progressed at least into the mountains to get T5 workbench, most people would upgrade or move on to another armour already, rendering Leather armour & Troll armour pointless (for most) early or mid bronze age.

The workaround would be either make Deer Leather/Troll available to craft at workbench lowest level, and upgrade as normal up to T4 instead of T5, making it somewhat viable for the stage of the game you would be at for that stage in progression anyway, bronze age.

Or, make a new Meadows tier or Black Forest tier upgrade maybe a sawhorse or sawbuck (bronze age) for the workbench to get the workbench to level 5 sooner, opposed to going to the mountains & swamp to get the materials needed for level 5. This, (to me at least) makes more sense and viability for tier if one decides to skip Bronze armour as an alternative.
