I've been playing since release for everyday. Now after many months I can confidently say that this is game is terrible. The worst part is deaf developers. They so listen to the players, it's true. However, they listen only to the whales apparently. There wasn't any major "quality of life" update at all. Even a few of those that were added, either makes no sense (like auto progress instead of skip & speed up buttons), or so minor, they have no impact at all (daily check-in indicator in the guild window), or tailored to the whales (black market with new currency instead of old). Developers also make new content tailored to whale level of teams, so as F2P you won't be able to progress far without paying a lot. Game is generous for the beginners, but once you reach 18th floor or so, you will hit CP wall. There is about 40 floors currently available if I'm not mistaken, and the amount will only grow. Your floor progress is tied to the story, so you basically won't be able to view it unless you pay. This also includes new content, for example ignition dungeon is require to have at least two 10 mil teams in order complete it. It's. A lot even for veterans like me. Also, there is tons of meaningless "beat the boss and get junk with a tiny chance to get mediocre reward" type of dungeons that only bloat the game while not offering anything rewarding for completing it. I could still go on with the rant since this game has a lot of issues, but I'm tired.

played almost 2 years and spent a some cash yet this game progresses so slow in some servers and yet new servers are merged to older ones and boom new content for them and we old players are trying to catch up to them. That’s the reason i quit. Dont play the game coz it will literally brainwash you through graphics

this game sucks, specially the rewards. Devs are just money milking players and they cant even fix the bugs.  every update has bugs lol even moderators sucks haha. i played this game for a year and decided to quit. I just stayed long because of my friends and now we all quit. this game has no improvement at all.
