after the new update, both the king and the queen got a lot weaker, as a result, the king's health only increase by like 42 per level and damage increases by only 2 while the queen only get's about 15 health per level and 4 more damage. These new changes makes upgrading the heroes more of a downgrade than ever, even compared to the old king and queen. To make it more balance, i think that the regeneration time should go up by only 2 minutes per level with a cap of 120 minutes
