I've been playing this "game" for more than 4 years and after I've seen the event of exchanging 5* heroes for a 5* hero of your choice I've deleted the game. I wonder who is so disconnected from reality to think that I would give 20 of my 5* heroes for 1 Gravemaker. I swear they had to employ someone with disability and that person ended in the event section because my god you have to be a special kind of person to pull something like this off. This is obviously gacha game and you have to accept it as such if you are going to play it but this is not just a gacha game it is the greediest filthiest thing in the world and NO! YOU SHOULD NEVER DOWNLOAD OR PLAY THIS IN YOUR LIFE, STOP BEFORE YOU EVEN START!!!
