Spot the difference between these two pictures:
The answer is in the title, after my DE storage is done, I can finally grind out 10k DE for my first BK level. With a lvl1 DE storage, I can store 12.5k DE so that’s enough for lvl2 BK. However with how bad DE is in TH7, it is unlikely for me to upgrade him quickly.
Dark barracks being built right there (7 o’clock in second pic), its requirement to upgrade to TH8 now so no choice for me to build it. At least its considered an offense upgrade so not much loss there.
