Great fun! Events frustrating!

Myself and my 2 boys really enjoy Madden Mobile. However I find it quite frustrating on certain live events when I spend stamina and receive nothing. For example: The Trophy Winner Reward pack. I spend all my 31 stamina amounts to 7 packs if successful and all I get is 6 bronze trophies and 1 silver. Brutal!!!! Fun game but rewards can be poor!!
