This all, of course, is working as intended.
Working as intended. Skip it or be prepared to spend gems and, most important, real life time (far more precious).
These Special events provide nice final rewards unfortunately whatever formula is used to provide balanced battles is ABSENT!!
Impossible to win once unlimited attempts section is complete. Regular battles, I easily beat 2,700 players, special events 2,600 players slaughter me! ABSOLUTELY NONSENSE
