I personally prefer defending the swamp :p, especially since you only need to use the spell removal once, and there are no mines:smile34:
But what does spell removal have to do with it? I said I like it, not that it's more effective..., although that depends on how you look at it ;), by the way, why specifically the swamp - the damage is the same, whether it's the swamp, Barbarians, etc.
And when was the last time that happened to you?:D
It's happened many times, depending on the mission or opponent, but more often in battles against enemies immune to fire
P.S. Could you upload a save file? - then we can discuss it :)
