Various members have floated this idea, of you being able to level up the items at Citadel Skillplots, so I just thought I'd float this here & see the response.
No doubt it will also lead to a fishing skill plot which is great news
it would be nice to get added as it could be an start for people to cap while training skills + invention. But if we want this to happen, they have to alter the gather rates of resources for all kinds of tools people have in their toolbelt. If we use our own tools it won't be normal people with bronze pickaxe gathering as fast as a crystal one
I'm not sure if it's possible, seeing as you don't use your own tools and the highest is rune (and anything over that like dragon and crystal is only cosmetic).
To make it possible, they would need to allow hatchets higher than rune in addition to allowing you to use your own tools, which would likely require a citadel rewrite.
