With the arrival of the Challenge Events having a wide array of heroes to choose from is even more of a thing. The reflected damage can be a real party pooper if it hits your team’s weak spot. Better have 2-3 heroes of each color to mix and match to build efficient compositions.
Hence the question is - what is the fastest, most efficient way to level up a lot of heroes?
- which province to farm for the maximum recruit gain? Is it 8-7 or are there better spots?
- which Training Camp options to use? The Uncommon for sure (backpacks), what then? Slow, extra slow, common, rare, fast, element, something else?
- is it better to focus on 1 hero and feed him the rainbow or spread the acquired heroes and feed them to their respective color brethren?
- any specific tips?
