I would like to be able to trade up defenders

Lizawesome

One thing that annoys me is when I have spent $ on a defender I need for an event, then after I get the next * up of that defender. For example, let’s say, I have a 6*defender, then right after I max them out, I get a 7* of that same defender. I wish there was a way I could trade in my 6* to level up my 7*. This game gets expensive and it would help on my wallet and frustration.

If you are spending in the game, you should definitely move away from ranking up 6*s
