Long time ago, I created a fully-levelled, 30 hero, 3* army, which is now roadkill on battlefields with 4* & 5* defence teams. This Rare 3 * army of mine is now obsolete.
It wasn’t always that way. I would like to see SG create two tiered Alliance Wars like they do for special events (rare & advanced).
I wonder how many other players have a rare Army mothballed (or fed them to hungry 4* & 5* heroes).
