Farming Ancient Legendaries in end game is a horrible experience;
-You can farm hundreds of Ancient Uniques in a day by doing boss runs.
-End game pit farming is useless, once all your glyphes are 100, Pits don’t offer anything, exept XP farm, and even farming Pit 150 dosen’t grant much XP, the end level rewards are deceiving.
-End game Nightmare dungeons are boring, difficulty dosen’t scale and drops are too rare.
-Undercity target farm isn’t worth the time unless you’re farming for Boss mats or mythic uniques.
The game is in dire need for a fun, engaging way to farm Ancient Legendaries; something like D3 Greater rift; Neverending Timed Tiered Rift with progressively increasing difficulty after each end level Boss, and a stacking buff increasing drop rates by killing elites; no random drops on enemies, just an end level chest that drops more and more Ancients Legendaries based on your stacking buff, before continuing to the next tiered level.
