I believe that there are certain advantages to imbalance
By the way, it was a mistake to abandon this in later installments.
In my opinion, playing the third game became less interesting due to inflation.
If in the second game the maximum daily profit from 1 Castle was 1250 (Warlocks had another +500), then in the third game 1000 -> 2000 --> 4000 (+ dwarf treasury) is very spoiling.
Unit growth also increased.
Personally, I get a feeling of permissiveness (money solves everything).
In the second game, I didn't always build level 6 — it was simply a waste of such money! I saved for bone dragons for a week! For green ones — about two! For titans — it's almost scary to say — a month! Now that was living!
