Awesome game but so hard earn loots – Defenders & Dragons Review

This is awesome i really like this game.,but there is something that I don't like.Loots,everytime when the missions completed i always get loots but not good loots and I really like to upgrade my hero but it so expensive and can lose loots so easily!I having hard time getting loots because I want my hero to get tough and upgrade them strong and the missions it going to be very difficulty soon and I want to prepare I be ready and then later when it started i been defeated so easily and I'm so frustrating I upgrades them as possible i can and I haven't left to get loots in difficulty missions so please fix this things right and little easy or medium because it really hard time doing this!!!
