I would like to make aq formal complaint to Gree. many people have expressed that 1 week is TO SHORT for heroic mode event. the ONLY way to complete it in a week is to make huge in app purchases use lots of gems for he4alth refills to keep fighting, star shards DO NOT DROP OFTEN ENOUGH to allow us a week to complete the quest!!! we know why you are doing this. TO PANDER TO THE BIG SPENDERS. this is completely unfair and you are ruining the game by refusing to listen to your feed back and serving ONLY the big spenders of this game i am really upset. you have made this game impossible for free players who wish to EARN everything rather then purchase their way through the game!!!!!!! PLEASE EXTEND THE HEROIC MODE EVENT TO AT LEAST 3 WEEKS!!
