Increase Tombstone Elixir Gain
Already did a quick search*, and didn't see this idea being posted (*quick search, so could have easier missed it, but doesn't seem common).
Something to help reward players for having good bases is to increase the Elixir gain from lost troops on their base. It would give a percentage of the Elixir cost of all the troops destroyed, and clicking on the Tombstones would collect it all. At least one Tombstone would be made for such a feature, since there isn't always one generated with the current setup. A collect button could also be added somewhere I suppose as well.
Win or lose, if your base put up a good fight against a strong army, you will get rewarded for it. Got 2 starred from a dragon raid? Congrats! You have a load of Elixir for your troubles! Got raided by Minions that grossly underestimated your defence? You just scored on some dark Elixir!
Have yet to think of what would fairly give gold, but guess that can be figured out later.
Clan Castle troops I can see being added to the total, since the cost for so few troops tend to be so low. And you cannot guarantee when and how you get attacked, or if CC troops get destroyed in the process. Even if you have a dragon, it would be the percentage of one dragon, which may or may not die, and you need to be attacked in the first place to 'claim' it's Elixir. Besides, some people have plans for those troops, get attacked, and lose those troops. They are out the troops, but get something in return. Guess it is like a life insurance policy for CC troops.
