I’ve recently been told that
… to get more 5* you need to have a lot of leveled 4*, the more 4* you have the higher the probability of getting a 5*
Of course, this can’t be true for summoning since the probability have been published. It could be true, however, for TC20.
I had never heard of this and I’m tempted to say that the number and quality of heroes you have has no influence on what you get from TC20.
Had anyone heard something like that?
