SORRY before Kamikaze.
And for the future, could the tournament rules be permanently changed so that a defeated or killed hero can never be bought back. Allow buying back a hero only if the hero fled the battlefield or bought his way out! I think it would be more interesting that way.
Sorry, but I absolutely don't see the point in this. At worst, you'll just have to constantly look for a hiding place and think a little more about who to attack and surrender to. No, I think the rules should remain as they are. I haven't used this rule in this game myself, but many players use it to the fullest. And it's simply indispensable for quick movement to the castle.
