it's quite difficult to break through there when it's relevant, and the turquoise one is just incredibly annoying, especially considering the map structure, where his heroes with the logo literally reach the portal leading to the center of the player's territory after just 2 turns after being resurrected. It's not difficult – it's just inconvenient. You could adjust his growth rate over time, but let him be resurrected less often, say, in 5-8 days, depending on the difficulty.
Okay, I'll try to do that.
