So there is a change to scribing scrolls from Arcana being a required skill to Arcana or Calligraphy Tool proficiency.  My Scribes wizard is teamed with a Wildfire Druid that had zero interest in learning Arcana to fuel my gotta scribe them all mentality. Would drawing pretty runes on trees or mushroom circles be more in the wheelhouse of the non arcane casters? Is a tool proficiency faster to learn than a skill?

 You don't really learn tool proficiencies or skills in the game. As you make your character I believe backgrounds give you your tool proficiencies and class (maybe background) give you your skill proficiencies.

If you aren't proficient with a skill, you are still assumed to know that skill. Tool proficiencies are different. I think you would need to take the skilled feat to learn more tool proficiencies. 

I believe Xanathar's Guide to Everything had a section about learning skills and tool proficiencies during downtime.
