DE 80k yesterday, 157k today. I still need to wait some time before any hero wakes up

Some builders coming free in another day, so I just started an elixir collector instead of continue to work on defenses. Collectors always generate loot, defenses never produce any loot at all.

BK going to wake in 2 days and my DE is only about half a day before its full. This is my main problem while playing this game right now, just wish I could spend all my gems. Its not worth it for now though, so I will just have to persevere.
