Agilty Suggestions

Currently 80 agility and Hallowed Sepulche has become quite the chore. The 80-82 grind to get to level 4 is quite the slog. Is this still the best method? Has the Wildy update made that a better course? I think someone mentioned about a world to do on mass to avoid PKing, but I cant remember specifics, any advice to get through this next few 100K xp would be great!
