I never zapped either. Got bk to level 5, got dark elixer troops upgraded, etc really quick. I got zapped many times though. at first i was like what the frick is this? then I was like oh i see they trying to get my DE. Usually I would revenge and take even more of there DE.
Its not hard to get DE at townhall lvl 7 if you got good tactics and know how to drill through walls. Id be getting through 3 and 4 layers of gold and purple walls with only 3 low level wall breakers. advance looting tactics 101.
