Well, if there are no hydras in the swamp, there's nothing to do there. I was really looking forward to gnomes in the elven faction, so I don't want a gnome castle either. I think elementals will be too strong if they're all in one castle, so let them be orcs – I don't like playing as them, but I don't mind them being in the game. There's no stronger destroyer than an orc enemy.

P.S. If they don't add cyclops to the orcish castle, I'll jump on the developers and bite them (they're one of my favorite creatures).
