Hello, I would like to propose a suggestion to make sovereign defeats a bit more important.
Right now when a sovereign is defeated, the only consequence is coming back to the capital, being paralized for a few turns and paying a small amount of mana. I understand that not killing the sovereign (or the champion) is a good choice, but perhaps there could be a more meaningful consequence without having to resort to death.
My proposal is that when a sovereign is defeated it causes a raise of 1% in unrest per sovereign level (with a minimum effect of 5%) during, let's say, 10 turns, or alternatively during 1 turn per sovereign level. After all the whole kingdom is shaped after the sovereign personal influence. Those people came to the cities following the sovereign, and if the sovereign gets defeated that will negatively impact their mood and, as a consequence, they will produce less.
The second part is the prestige reduction. A defeated sovereign has less personal appealing, and he/she will attract less people to his/her kingdom. That's why faction prestige would suffer a permanent penalty of, let's say 0.5 or 1 prestige point.
Maybe champion's defeats could have similar effects. Of course not so big as with sovereigns, as champions are less important. Let's say half the penalties.
What do you think about this idea?
