as someone who has been playing this game for yrs, some parts of the game still feels slow like buying a new dragon and upgrading it all the way to highest if you are above 150 dragon level even tho the devs brought a system to upgrade it inst to lv51 it's still frustrating and takes too long especially if you have many dragons, my req to the devs is make levelling up instantly according to the players dragon level except for the valka training, but overall a great game 👍🏻
