Stop Regeneration Please

I'm wondering if you guys could stop regenerating a boss if you don't kill him off the first time through? There are bosses with 13,000 hit points that my toughest guys cannot kill. They whittle down his points, but don't destroy him completely. And then the next attack, he is back up to full life again! Why? He regenerates instantly, yet I am stuck waiting forever for my guys to repopulate. I keep running out of time for these adventures. Can you either stop regenerating the big dude or speed up the repopulation of my army or allow more time for the completion of these adventures? Thank you very much.

You have to step it up man and start using better soldier's, that is the way it works.

maybe not even better soldiers, there are guides everywhere you just need the right combo of people to attack bosses. Bosses kill cav first, any meat shield aka rec, militia, soldiers, and elites, then they kill bowmen so just look up a guide. Regeneration is part of the game for a reason, as not to cheese the heck out of bosses, thanks- HWER

If a change was instituted to have bosses not regenerate, then another change would have to be made that the defender be able to recruit more troops. Currently the bosses can't do that. That is why you have a cool down period and the bosses don't.
