Same experience with our Cabal, we've actually been extremely furiously pissed off about it and we're hoping its due to just incredibly shitty RNG. We've basically given and decided to not even try this week for the directive because 110 unholy codices is basically a big middle finger. Even with a full Cabal of 20 just farming the crap out of chaos missions (if they're even available) for the insignificant chance that a sorcerer might spawn and then the even more insignificant chance that we'll actually get a real drop. That could mean x1000 missions. Any of the other directives can be done in like an hour. This was outrageous. If they've changed all of them to be similar in difficulty then we're just going to give on even paying attention to the directives.
