I dont know you, OP, or the rest of the players, but the best advice I can give is be patient. This isn't another RTS like Supreme Commander or StarCraft where you have to rush everything.
Sir, I can't tell if you're being sarcastic or condescending.
Just keep close to main base for a good many turns until it's got a big inf ring. At least then monsters will spawn far away from your sttelement rather than adjacent to it. Make sure al lyour guys have god move. And then just troll around your place killing dudes til you get a decent defender.
Now I'm really beginning to wonder how many people actually read my OP. I HAVE NO TIME to be patient. The group of five spiders that crushed me on turn 10, or the three bandits that circled my city and wore down my defences didn't wait to attack every three turns while I built a new defender.
Also, if the opening strategy for a game that includes things like quests and the hunting down of glowies for a crucial advantage is to sit on your butt and build for 50 turns, then something is broken.
I have been playing this game since it was released, and in all the versions I've played I've never felt this defenceless in the opening turns.
