Hey all,
I have been playing roughly 3 months and find I am now stuck and cannot complete any available content without needing to use a ton of units. I am currently at 5.3.2, and have fully explored acts 1-4. I tried getting through the waning moon variant but needed to use all my units to get past 1.1 and feel it's impossible to break through. I am currently just grinding arena, but have no idea how to get my champs ranked up enough to keep questing. What should I do?
My roster is:
5&6*:


4*:


I purchased a few Odin chests during cyber weekend and over the holidays, but do not want to be spending.
I feel my alliance is not the greatest and would be open to a change for one that is more active and perhaps a higher rank.
If anyone has any thoughts, it would be much appreciated as I am slowly losing motivation.
Thanks!
