The midgame Smithing grind was the worst offender in the game, and this update tears it down. Metal bars no longer need logs as fuel. You smelt with ore, plus coal from steel on up, and nothing else. Forging tools, weapons, and armor no longer needs planks at all. If you want a chestplate, you need bars, full stop. No side trips through Woodcutting and Crafting just to start smithing. On top of that, smelting a bar is now a single action and grants far more experience, so it is finally worth doing on its own. Start to finish, the smelt and forge loop is several times faster than before.
Cooking, Crafting, and Woodcutting all had their experience rates raised to sit in line with the rest of the skills, so no single skill feels like a slog next to its neighbors. Cooking also burns less food while you are still learning a new fish, so more of your catch makes it to the plate.
Cooking no longer eats a matching log for every single fish. Instead you choose which log keeps your fire going, and a higher tier log burns far longer before it needs replacing. A single elder log now fuels dozens of cooks. Your woodpile goes much, much further, and a new readout on the skilling bar shows the log you are burning and how many cooks it has left.
