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.
