I think we are missing a clear idea that a painter DoH class could do, tattoos. A lot of people like the gear that has tattoos added to their designs and a painter or rather artist can do that. I think the name painter is what might be throwing people off but if you think about all thr things an artidt can do you get a lot more than just paintings and dies.

Tattoo designs for head, body arms and legs
House paintings
Outdoor sculptures
Outdoor murals
Dyes (new ones)
Sculpture minions
New mats in the form or crafting dyes (for crafters to use, not us), turpentine, blown glass, painted silks, paper, etc
If we ever get "buffing" items for the jobs, artists can make new cards for Astro, talismans for Ninja

And I am sure there are other items that could be added, but my well has run dry, T.T
