I think the problem is that there’s gear out there that is so good that people always want it with each increase combined with the nature of the cap increases versus amount of content in the game. Traditionally in MMORPGs for example, level cap increases came with large scale expansions of content and mechanics which meant that you weren’t refarming your same old gear, but instead working to a new better set each time so you aren’t farming what you already spent hours farming before.
After a certain point it’s not about having stuff delivered onto your plate as some people call it, it’s about not wasting your time on something you already have. But in all honesty, it would be so much better if they just reworked anointments altogether and made them something you put onto a weapon yourself instead of dropping with permanent anointments as an extra layer of rng.
