Paragon's End Game Approach

I want to come back to a topic that I mentioned earlier and that is a bleakly referenced end game through Paragon. So, what makes a compelling end game approach, in your opinion? Well, when the player reaches end game, there's sort of a moment where something is stopping like a campaign or other systems are starting. And so, I think you want to have those things feel like they are interesting and not merely things that were added on. Make sure that the endgame presents even more interesting choices for players to customize and feel powerful.
