I really don't want to see fixed and predictable mob locations that drop specific items, like runes. You want runes? Get the resources that you can already gather and craft them.
We already are going to have plenty of pvp opportunities with resource nodes, outposts, Forts, Castles, and possibly new captureable POIs that we haven't seen yet.
More PvE content in a PvP oriented game doesn't really make sense to me.
I don't even see the point of bots in the first place. There is no auction house, you have to start from scratch when going into a new campaign which is a new world where resources and harvesting locations will change rapidly so there are no efficient farming routes like there are in other MMO's. Anyone trying to farm resources would literally have to just play the game and all non-vaulted resources get lost the moment the campaign ends so it's going to be extremely hard to hoard up enough valuable resources to interest other players enough to want to pay money for them.
You would have to play through a several month campaign just to hopefully get the chance (if you win) to take some resources with you and then hope that you find a player dumb enough to pay you a few bucks for them. That is not a reliable way for traditional gold farmers to make any kind of money.
The only thing I could possibly see people selling for cash would be valuable manufactured stuff (valuable weapons, armor sets or maybe plots of land for EK's) but in order to get those in the first place you would need to invest a lot of time in the game, and those won't sell for nearly as much as in other MMO's due to the fact that they will break in time.
