Why play Kingdom when you have Empire Spy?
To me it seems the most over powered aspect of the game currently is the Spy summoned creature. If multiplayer launches with this creature intact there would be no reason I would ever choose the Kingdom side.
Think about it. It's a relatively easy creature to get and has an immediate AOE that does 10 dmg to everything.
With the current health pools of the Champions you could easily take out 4-5 Champions AND the Sovereign within the first 2 combat turns.
Can anyone think of a balanced ability on the Kingdom side to counteract this creature?
