Troops tend to regenerate slower than spies. Click on a troop building and compare that to the regen rate of a spy building.(You will notice that your spies have a higher regen rate.) More Info: - Spy Buildings also gives you more troops than those compared to regular attack troops. Happy New Year's, Everyone. Happy Kawing, Everyone. :-D
You have a balanced troop building giving you two more hits per full regen meaning your full regen takes longerbb
It takes 13 regens for troops to fully regenerate (1 hour, 5 minutes) and spies only take 12 regens (1 hour flat)
