That is a nice summary of my whine - I agree, my feedback wasn't very constructive, I was a bit frustrated in the moment!
I do spend money in the game, because I am happy for the game providers to get revenue from it, I just prefer to try and keep it in proportion. I am not bothered about the cool down period, because we can speed that up with a reasonable spend, and even without it spending, if the escape rate was lower, you could still do 3 boxes in a day, which would get you there.
It is the cost and number of troops, coupled with the escape rate that quickly adds up here, meaning I can only do 2 boxes per day on my budget.
