I like the thought of helping a friend but I don't like using my boosters. I get nothing in return for helping plus that person still might not be able to pass the level even with the additional boosters sent to them. This seems only to reduce the amount of boosters from my inventory if I needed to use them to help the friend leading to me believe it's another way to encourage me to buy more boosters to complete my own levels. Luckily for me I have massive boosters therfore no need to buy any additional boosters. I'm sure this is a test and hopefully King could find a better way to help without using your own stock of boosters. I just don't like it.
