It’ll be interesting to see how it works out. The fact that there is a cap on paragon points, combined with the level scaling, seems to be a design choice to discourage chasing power on one character. You can be mostly “feature complete” with your build by 60 or so. I think the success of the model will depend on how interesting the seasonal content is to engage with, and if that outweighs the annoyance of making new characters.
