Hi Dras6fin,
I like your examples.While I'd love to have different ways to "Restore" the nodes depending on Grade, I'd be happy with even 1 new type of activity / mini-game per class as a start.
If you think about it, unfortunately, for all Grades of Nodes right now, a Botanist still only has 1 command to "Log / Chop". Same for Miner, Fisher.
So as a simple start, it'd be great to give us just 1 type of New Activity per DoL Class. Eventually, sure, I'd love to have different ways to Restore depending on Grade.
Maybe, your idea to have "Grafting" can be for the Main Hand Nodes (like Trees) and "Replanting" for Off Hand Nodes (like Bushes / Harvesting Points), etc.
