I'm excited that openworld mobs may actually be challenging. I'm sure they aren't going to make it overly hard though. There is no way they will put super-hard stuff in the way of say storyline completion or anything. I'm also hoping that these harder mobs might drop some good crafting mats and that farming them with a friend might make some money.

I feel the further away from civilization the harsher the zones and mobs should be.
