I have heard that already, halas. Hey level design is great, you just have to get used to it.
Stealing and exploiting the rules are a good way to go in this beta. Murdering merchants and NPCs is also a great way to get new gear and XPs. I hope you like roleplaying as a thief and murderer, it makes things so much easier.
And some character builds are easier to play with than some others. And the good choice of talents makes a real difference. Don't waste your points in anything that is not totally dedicated to combat, it would be a terrible waste of time and effectiveness...
And keep in mind you are noob source hunters, send on their first mission. That way, you might not be to overconfident.
