Greater Rits are more akin to scoreboards on an arcade game than leaderboards. They serve basically no purpose for improving your character, and are purely optional.Quote from DorakrabHows Gr100 for endgame? At least 50 at this point in the game (solo)
While challenge is an important part of endgame, I make the distinction that a proper endgame has to have interlocking systems of progression and challenge. If your "endgame" content offers the same drops as everywhere else, it's not much of an endgame. Likewise, an infinitely scaling statistical system is more of a curiosity and time-waster than a structured challenge.
