The endgame is in dire need of a complete redesign, but it's still far better than the campaign. I honestly have no idea how people complete it in 4 hours, every time I slog through it I feel like it takes at least twice that in just walking time. At least in PoE1 I can look at my level and the zone level and understand that I fucked up and should have skipped a lot of the stuff I killed and it's my own fault for being way overleveled, but in PoE2 right now I'm not even overleveled and it still takes ages to get through each zone.
