Been playing for a year and using my crystals on ×2 and ×10 summons and in that time I've gotten a grand total of 4 legendary characters. It's 100% pay to win unless you want to spend 4-5 hours a day to unlock the bare minimum of material. The graphics and fight mechanics are the best in mobile gaming but to get anything you gotta spend that money! They responded with a sorry reply. To get free shards you have to spend countless hours playing. I'm talking ALOT. Flooded the hero pool=bad odds
