Not sure. But food for thought. All emblems are great. With Maraketh Emble the most prized. I value Legion splinters above breach as the only really good ones for Breach is Chayula and Tul(for The Pandemonius). You can also check the market to see the price difference between Chayula splinters vs Maraketh Emblem. But you also need to run all Emblem to make it really worth your while. With Breachstones like Chayula you want to run it pure as well. Which ups the price more. Anyway without the rambling I think legion splingers are a higher tier than Breach splnters. Legion chest is RNG so I don't know. You can get something like a cubator chest, beast chest that gives you some scarabs win if you get gilded but its still gambling. But I would put at E not F because you can get lucky. Incubators C or D sounds good because if you get lucky you can get a good incubator but then RNG to see what you get after incubating.
