Blizzard says that by endgame, players will have 30-40% of the skill nodes filled and that’s intentional. Players will not be able to acquire every Skill Tree node during their playthrough.
The developers also touched on the endgame plans for Diablo 4. While Blizzard says it’s still in development and there won’t be specific details anytime soon, the philosophy for the endgame is to give it more depth and replayability than what is currently available with the Paragon system in Diablo 3.Paragon essentially makes it so players kill monsters to grind out small improvements for their characters. While there are no details about Diablo 4’s endgame, Blizzard wants it to be where the “easy to learn, difficult to master” idea comes most into play “where the difficult to master component will come in and should meet the expectations of the most hardcore Diablo players out there.”
