I read some topics about emblems strategy on 4* or 5* but rarely I see explanation when 20 level is worth to reach.
I see suggestion about teaching level with mana speed with troops lvl 11 or more.
Other answer is to distribute emblems among different heros in given class. But then—as I understand— you have bunch of equal cards wihout one superior.
It is especially confusing when you have divergent set of heros from 4* and 5* — as there are suggested hero who should be equip with emblems but no explanation how far it should be.
I read that for someone the rule is 6 level, but explanations are missing.
Therefore I wonder do you have some other guidelines in this respect? What are your decision criteria for going to full emblems?
