To be forced to farm Fates (community has deemed to be a serious problem) not only once but twice for two sets of drops that don't even overlap in their drop rates. All those people who have gone weeks and months without an Atma drop now get to double down on that experience with Alexandrites and this is completely ignoring the Myth farming.
You're not forced to farm FATE's at all. It's purely optional how you approach the weapon:
- Daily quest/Roulette for map
- Buy map with 800 Myth
- Farm FATE's

Personally I think this is much better than pure the myth grind for Animus, if you were to do only the daily quests that's 75 days. If you supplement it with Myth purchased maps and FATE's, it's going to be much quicker. Considering it took me upwards of 60 days to complete my Animus books, this seems pretty reasonable. When you compare it to both Atma and Animus phases (a 10 level rise too) it's WAY less work in total. If you choose to only approach it by grinding FATE's or grinding Myth, then that's YOUR problem, not the development teams.
