I farmed about 45k DE last few days, then lost 4.4k in consecutive attacks waiting for lab and builders to free up.
So I cleared out my core and decided to add a moat with traps around my DE...
sneaky AT funnels have been around since mid TH7, though without a corridor the giants sometimes tiptoe around the spring traps.
