Blood pit / Betting
Just a quick thought, In the future perhaps players can enter their hero and/or troops into a blood pit type arena thing? The town would be neutral to all and you can place a wager, if you win you get some winnings, if you lose... you lose. You would not lose any units in this pvp but they will get hurt and have to rest after the battle. The arena would work like random matchmaking.. or you can set up a specific match. Could have a ranking to see who is king of the arena etc get some more competition going.
I was thinking maybe you can either bet crowns or gold.. crowns would be a high risk match though as they are valuable, but gold isnt hard to get so.. Troops would gain xp from this as well as hero (at a reduced rate)

Every morning orcs like me should have a good long battlecry.. to the tune of.. ahem.. 'WAAAAGGGHHHH!!' It prepares you for the looting and pillaging the day brings.
