I've been running the master lost sector (Metamorphosis) for the last few hours to try and get a better Omnioculus. One Sixth Coyote, TWO Ophidia Spathe, THREE Raiden Flux and numerous single enhancement core runs later, no Omnioculus. I'm nearing 3000 enhancement cores I don't need anymore. This is all my opinion for my playstyle, but Raiden Flux hasn't been super viable since add clear duty during the Calus fight; Ophidia Spathe is just an absolute waste with gamblers dodge and other knife-oriented exotics. As for Sixth Coyote, read what I said about Ophidia Spathe. It just isn't isn't as useful as other dodge-oriented exotics, such as Dragon's Shadow or Gemini Jesters. Whatever the weighting system is in the RNG needs to change. I'm over deleting Raiden Flux, Ophidia Spathe, Foetracer, Knucklehead Radar, etc, etc, etc. It's obvious that the RNG system weights certain exotics more than others, for all classes, and it needs to change. The time sink just to have no positive outcome is aggravating. Sure it's nice for lost sectors to grant the exotic you don't have, but once you have them all it's just awful.
