The game is all about loot. Whether a low level town hall uses or abuses his/her lightening spell for dark elixir(de), is completely up to them.
You cannot expect a th7 with lvl 3 or lvl 4 troops to gain access to a lot of de when up against a th9 or th10. That is the only other way they can obtain de.
As for using a lot of resources for de. I agree we use a lot of elixir for the de, however those spells dont come cheap either. So stop whining and enjoy the game the way it is being played. Rather appreciate the fact that people who play this game actually know how to use what they have effectively. Otherwise it wouldnt have been a challenge to begin with.
Fact remain, you complain about lower levels looting your de with spells, tomorrow a lower level th will complain about higher level guys flat lining there base and hard earned de.
So for those of you who have an issue with lightening usage, stop being self centred and try and remember how tough your days as a lower th level was.
