I actually took sweet time because I didn’t have Advanced Iron Storages ready, and also I needed lv3 training for feeders for Kage and Lianna. Now those are ready, and last remaining Food Storage is built in parallel with HA (VIP) and will be ready before HA lv 10.
But I have another question: it is worthwile to use TC20 when one has HA lv10 and enough 5* dups? I mean Lv10 is guaranteed to return 5*, so those remaining S1 5* I don’t have (Azlar, Marjana, Domitia, Justice) should be easier to get from HA10 than TC20. So most likely I’ll leave a single TC20 running as a storage for food and recruits and stop the others.
