You dont sound like a serious player to me, you sound like a Whiny child.

You cannot take someones last city, because its stated you cannot, end of story, loot it, destroy defenses, then move on.

If you attacked with a Scout "army" which im suspecting you did, yes you lose ALL of your scouts on the first round of battle... you CANNOT attack with scouts, they are for SCOUTING. (i also learned the hard way, but only lost 150 scouts)

If you lose the battle you have a chance of losing your hero it seems... perhaps not intended, but it happens.


so all in all...

Stop crying, and play the game.
