You know when a lot of players just use a few or so lightning spells on your precious Dark Elixir stotage (or other storages)? How about a building you can buy at th8+ called the Lightning rod? Here's how it works: it has 'x' capacity to absorb 'x' amount of nearby lightning spell strikes. So it will basically protect any nearby buildings from getting struck by said spell. If that seems too simple to exploit, it could just be put on top of a building and protect it from the lighting spell. If you guys like this idea, spread the word!
