It is a good game and I enjoy playing. However, event summons are very very unfair. Spend awhile saving gems for special summons, using 300/350 gems to end up wit heroes that can be claimed in daily summon. It is sickening. Everytime I save and spend gems in event summons i get rare heroes instead of the epic/legendary heroes I expect to get. Rare heroes should be taken out of event/special summons.
