Light troops = gold troops
As simple as the title. Rather then changing skins, how about a new barracks dedicated to gold troops. So many mid level bases have an excess of gold over elixir. Let's have some troops that use gold to train. Along the same lines as dark troops, some weak flying troops similar to minions, some fast grouping ground troops like hogs... etc... but all of them white and gold, little to no purple in their design. I think this may help even out the over use of elixir. So many players going broke on elixir in wars and such. This would be a game changer. Low on E, switch to golden troops. Low on dark, do a elixir/gold attack... etc.
