Alternative "Lootspot buff"
Many high level players have been using Ranged Support ever since in order to save travel time on lootspots, providing convenience both to the giver and the recipient.
Suggestion:
Introduce a new buff:
"Deadly Arrow"
Cost: 30 Star Coins
Effect: Kill 1 random enemy unit.
Can not be used on leader camps.
(Also available for 100 coins for lower levelled players)
This would save a lot of players a lot of irritation and would be a convenient alternative plus a good sink for (star) coins.
