Titanium is a silvered colored metal with low density and high strength. It is notable for having the highest tensile strength-to-density ratio of any metallic element. However, it’s not as hard as some varieties of heat-treated steel.
Titanium is commonly alloyed with a range of elements including iron, aluminum, and vanadium. Titanium alloys are strong and lightweight making them ideal for automotive, aerospace, military and industrial applications. Two-thirds of all titanium metal produced is used for aircraft parts. Titanium is also highly resistant to seawater corrosion making it perfect for propeller shafts and rigging as well as divers’ knives.
See my point. Using just metals on their own is....nice, but when you have the proper mix of different metals, you get a product that can be better than the sum of the parts included.
It's the same with many other things in game. Cul for example, you get some dinky looking ingredents on their own, but together they create a much different flavour, and the same items can be prepared many different ways to give you something different.
Take away some of these items and you don't have the proper end result, creating something much different. Metals have their own strengths. Cooking ingredents have their own strengths.
Did you know that if you dry the hide of animals, you get raw hide instead of leather, which is used ENTIRELY differently than leather? Leather is used in clothing, armour, ect. Rawhide is dried, not letting it be used the same way as with tanning the animal skin. Some one example would be old fashioned drums.
Do you think you could make a beef stew with chicken? No. It becomes an entirely different dish without beef in it.
Do you think you could make steel without iron? No. It becomes something totally different without iron.
Do you think you could go into battle with an outfit made of rawhide? It doesn't offer the same protection as tanned animal skin, aka leather.
Personally I would be saddened if they got rid of items to make it simpler, and I would honestly be a bit insulted, as someone who loves to cook IRL.
Also did you know that iron oxides give many types of makeup their colours?
Then I suggest you stop using peoples' lodestone pages as a means to harass and belittle what others are saying. Just because someone might not craft to the extent you do doesn't mean their opinion is in valid. You're not the queen of all facts. The Lodestone is not a weapon. I suggest you stop using it as one lest you make people dislike you.
I know people in game that do nothing but craft, but they manage to work with the space they're given in game. Maybe you need to better prioritize what you're working on? You may think you've priortized it properly, but if you have as many issues as you say, I'm sure you can do better.
