How about adding statistics for how efficient your attacks are?
For example,
A crystal league 2 player with a TH level 10:
You searched 10 times at 1,000 gold (10,000).
You used 50 archers at 200 (10,000) and 10 Giants at 2,500 (25,000).
You stole 50,000 gold and elixir got 1 star with a match bonus of 34,000 gold and elixir, 100 dark elixir and 5 trophies.
Subtract the total investment (10,000 gold, 35,000 elixir) from what you gained (84,000 gold and elixir, 100 dark elixir and 1 star) and you net gain was 74,000 gold, 49,000 elixir, 100 dark elixir, 1 star and 5 trophies.
