Just LoL I mean one can make wishful suggestion, but this is just so stupid that either you havent played the game or a noob who hasnt reach 2k might.
Not only that the timer is there to prevent endless shards, but also xp and hb so, even leaving hackers aside, every player that dont suck will exploit to its fullest.
sorry people should either play well or get lucky or invest lots of money (support us nonpaying players) to be a high ranked player and not some no-life kids/bots who nonstop run the dungeons
Better make the max dungeon runs from 5 to 10 so one can do these runs every 3h without missing one, decreasing the refresh time to 15 would just be more annoying for those who dont spend their life on the screen of their smartphones. Its a mobile phone game so one should play once in a while and not every hour
Another idea would be to have a fixed amount of dungeons douable per day.
Like that if you only have 2 hours a day to play the game, you could try to do as many chances as you can without spending your day looking at your phone to see if your chances are rdy lol,
IGG doesn't care unless it involves making them money. The current system promotes people refreshing dungeon chances with gems and it reduces the amount of shards you can get, which means it's harder to get legendaries for free. Don't expect IGG to do anything that involves reducing gem purchases.
