Nice to see we're getting Anya's revival now. Though I wish we had the 100% guaranteed first time drops because farming for those 'moment crystals' is going to be a pain if we don't get a good head start. For Anya, we need 800 MCs for Dorania and Fleur. Aria is also a good choice which I will definitely try to mincost since Lieselotte's event is getting pushed further back with the devs giving us old unimplemented events now. I hope we get the 90/12 map for both parts of the revival to get 24 MCs with a high drop rate. Sucks that we don't have a thief class yet to increase the drop rates of the crystals.

From what I heard during Anya's revival at DMM, Aria's 90/12 map is better than Echidna's 90/12 map in terms of difficulty, so I would use this week to get Anya and possibly Aria mincosted.
