I think what happens to is since the game been around for years it seem to promote lazyness. Designers kinda reach their end point of hey this did well for x amount of time and that was my goal. This or any game at some point sadly faces this

With said goal gone its more of just adding bits and pieces of crumbs. Like when it comes to story content we gotta be waiting 3+ months and while I love cliff hangers it gets annoying waiting too long.
