Making best in slot gear would be crazy. When it reverted barrows and RuneScape gold dragon material even making level gear good enough would be awful. Gear that is rune and black d'hide is great enough to be the best for crafting. How that you use smithing in large level gear is currently assembling rare parts dropped. Godswords shield+variants such as magical & ranged, Dragon sq+kiteshields and platebody, crystal equipment and maybe some others. And you're able to repair your barrows armour for cheaper with smithing level that is greater.

How is any of the aforementioned suited to crafting? Historical blacksmiths created nails, horseshoes, gates, fittings, hinges, railings etc.. Largely anything iron/steel. If anything is mislabeled, it is the final portion of jewelry crafting procedure. Could probably be considered smithing instead of crafting. Crafting ability could techically consist of structure, fletching and smithing, but mixing them is not something which can be achieved anymore.

Crafting can be separated to leatherworking, tailoring, pottery, weaving etc. but it's not really something that can be done at this point. If it were that way from the start it could have been. Every one of these could be expansive skill on its own. But obviously they all are stripped down in their current form and probably not enough to be their skill. They'd need more information developed for them specifically. Structure, fletching and smithing have content created for them than the skills crafting now consists of.

In other words, I would not overhaul. Changing what's there breaks to be well worth it. Rather, I'd add alongside what is currently there with more level equipment. At Level 55 or 60, perhaps By runescape 3 gold way of instance you could make a brand new metal from Mithril which makes a Level 50 Armor. For example, an steel in 35 that makes level 25 equipment, a brand new mithil let at 60 that makes. They would not need to be full sets; they might only Concentrate on armor and Some of the weapons and just span say 10 levels (e.g. dagger, med helm, sq shield, sword, mace, complete helm, kiteshield, scimitar, platelegs/skirt, platebody Might Be an unlock each level)
