Endgame is repetitive and boring

I reached lvl 88 some days ago, right now the will to continue farming has gone. I want to play, to progress, but its so boring. The one shot hits/explosions that you dont see coming are frustrating, cause you lose your map keys and exp, dont feel deserved.
I look at the endgame map, the magic is gone, all I see is an empty map, with the same activities I've already done a lot of times, there's nothing new, its like Diablo's rifts but dressed another way.
I've still havent found those citadels to get the keys, and I've "explored" a lot the map.
I'm relatively new to PoE, I dont fully understand what are Delirium, Rituals, Breachs and Expeditions, and theres no explanation in game. I've been doing them, but I have to collect 300 fragments to attempt to kill a boss?? I have 24 in 160h gameplay time. I still dont know whats the point of expeditions and I've done it a lot of times.
Another point, I dont know if its a bug, but I have +2 map boss difficulty, but the maps dont get these lvls modificators, like when the map have corruption or is irradiated. If its by design, I think the map should apply the + lvl, so the mobs give more exp and we dont feel stuck.

The campaign is excellent, the story is compelling and the maps and bosses designs are incredible, I wouldnt change a thing.


Maybe I'm too casual for PoE II. But my sugestions would be, so the endgame would feel more compelling:

- Change how Breach, Delirium, Rituals and Expedition are presented in the maps, make the maps more related to it, instead of just "throwing them in". Explain better what is the point of doing these activies, so new players dont feel lost and unmotivated
- Dont lose the map when you die, modificators (boss, irradiated, corruption, etc) would still be there
- Reduce the amount of fragments to challenge bosses, 300 is an absurd (and its an attemp by what Ive heard of, right? You lose the key if you die? If it is, change it so the key is only used when the player defeat the boss, and then have to farm it to fight him again)

I'm sure there a are a lot of good ideas in this forum on how to improve the endgame and other aspects of the game. PoE is awesome, and I hope you (the developers) take your time to read through all the feedback the community is giving.

Just to be clear, I loved the game, and only took my time to write the feedback so it can become better. Thanks and Merry Christmas!
