Heroes Dropping Items

Whenever the barbarian king or any hero dies he never drops anything to take. Like The archer gives elixir (tombstone) and others too and drak troops give dark elixir. Please One of these things or all:-
1. Gems
2. Elixir
3. Gold
4. Dark Elixir
And Please send these to the treasury.
The Higher The LEvel The Higher The loot.

Since they are made of dark elixir that's what they could drop, but the problem is the tombstone reward it's broken at this moment , since an barbarian that costs 100 elixir drops 20 into tombstone, same as for a pekka that costs 30-40 times more.
