This may seem like a mismatch but I've been using Atheon's Epilogue over the past two weeks in regular Crucible and it is very strong. I have used the majority of Primaries and for me personally, it comes out on top.
I don't have Doctrine Of Passing but I have seen how good it is. If Doctrine is better, I have to get it.
If you have both, try them out and vote.
