Facing dragon early in the game is suicide, later in the game it can be fun and challenging fight. But when I got fell dragon on my side the game became boring. That thing would cast fear on everybody then walk across the map and kill 5 units at once with fire. Very often by the time my enemy would be able to make first move most of his army was long gone. The only challenge for that dragon was that huge leviathan looking monster. Cannot remeber what it was called.
