Why nerfing checkpoints?

I'm still in t10 maps, but checkpoints have clearly been nerfed. I ran about 3 crypts in the last hour and literally haven't found a single checkpoint in the maps (with the exception for the one right at the beginning at the boss one). It's a maze map, quite annoying to traverse, so checkpoints would be really useful.
More than that, I like doing rituals. In the past seasons, once you finished the 4th ritual in your map you'd get a checkpoint (which was quite helpful to be used to tele you to the boss map if you foun its checkpoint). Now you simply don't get which means most of the cases you'd need to run back a lot of the way you progressed to either find another checkpoint or walk your way to the boss.
This is the kind of QoF issue that's really concerning
