I had a problem with my smatphone. It was crashing constantly and I had to back up several times of the game so as not to lose my progress. But that's no problem with the game.
The doubt is that in doing the backups, I realized that in "Big Bads" the game is programmed to ALWAYS give me the following rosters: Deadpool; Coulson and Jean Gray.
If this is correct, I would like a clarification on the question of the percentage chance of getting a 5 * character.
