In legends, I have no problem keeping all of them busy. My point being, there are multiple ways to farm effectively.
I dont need books. I can use CWL medals buy builders potion. As soon as I have four heroes down and almost maxed on resources, I use builder potion to finish up quickly and goes to next cycle. This way is much cheaper than 165 medal for one hero level. At the same time, lots of gold and elixir goes to walls. So I can do CWL with all maxed heroes (hopefully I have enough time for farming).
