Favorite enemy

[BB Shockwave]

I am using only human units too, so yeah, this sucks.

My idea is - which I will try out when I get more money to experiment - that if you merge two similar groups, the Favorite enemy ability of the bigger group will stack to the merged group. Meaning, you dismiss/leave in a castle more then half of your old troops, hire new ones (more then half of what you can recruit), attack an enemy you think will fight often (Black Dragons, for example) and then go back to the castle and merge the two groups.

Or, if you have enough money, just dismissing the old group, buying new ones and try to find an enemy where you will be able to attack a new favorite.
