Uhm, mazes, platforming, 6 man team work, intense and complicated boss mechanics which can all be beaten with countless different strategies other than "melt the boss with gally". Vault of glass atleast was interesting at first. Poe is the same shit wave after wave, with some stupid reskinned boss thats usually just a bullet sponge. Both raids are far more fun then POE, Only think poe has going for it is that its very difficult to cheat.
