You are confusing me now, don't we have 2 weeks to farm for the crystals?
We should have more than enough time plan properly.
You don't need awakened units to do anya's questline, just look at the guide, they use only CC-ed units.
Anya came out in 2013, it is quite doable for everyone.
My new 1 week old account has cleared all her quests with the exception of the final one.
