I was reviewing https://atlascalculator.com/ and listening to other company members talk about the requirements to unlock trees like Piracy and I think that two simple changes could greatly improve the talent trees.
1. Remove the requirements to unlock talent trees and remove the talents that are used to unlock those trees.
2. Make a cleaner interface for those trees. The Atlas calculator is a much cleaner version of the talent trees and is much easier on the eyes and easier to see the flow of the tree.
