The fact that low tier affixes aren't removed on high iLvl items is the biggest offender here. High iLvl affix pool is too deluded with low level affixes. It's a typical combinatorial explosion problem - rolling (1-8 tiers)^6 affixes where 70% of them are garbage creates the situation of astronomically unlikely outcomes.
Which proves that GGG is a morally bankrupt company. They understand very well what they did by introducing scourge. They don't want you to enjoy the game, they want you to become a gambling addict. Scourge is not for 0.1% players, it's for no one. Even top no-life players like Empyrion have only 1-2 scourged items equipped, which proves that the best scourged items cannot exist.
Gear progression is broken. I leveled 4 characters to ~85 level and they keep sharing the same gear between each other. iLvl 65-73 gear which cannot be upgraded without multiple exalts which I also cannot get despite trying every possible farming strategy.
Right now the game feels too grindy and unenjoyable. Uninstalled.
