Hi! I’ve been playing about 2 months now. I tried searching for this so please forgive me if this common.

1. Is there any benefit to upgrading bronze and silver units? I’ve stopped leveling most of them between 10 and 20.

2. The last 2 all star challenge modes, I’ve been stopped hard at 64-66. Do I just need stronger 4 star units? Or is this because of my lower level units needing to be leveled more?

Thanks!!
