My idea is that you have the option to donate troops out of your camps like normal.
OR
donate the cost of a troop eith an added 25% to it, this extra cost would cover for the time it takes for it to train.
To use this feature you would simply click on a grey troop and a pop up box would appear.
E.g. Would you like to donate archer for 250 elixir?
this feature would encourage more donations and make it easier to donate the troops requested.
