In contrary, the mechanics could make the community "care bear". As in make the noobs too valuable to kill, leaving the big boys to fight over the attention the said newbies.
Jorb has posted a while ago that they are aiming to make the game suitable for open cities where noobs could come and wander in safety. They have also expressed thoughts of making the hermits more valuable or not worth raiding as well.
@displaced, you're describing the game to your friends in a way that they will 100% loose their character. I am almost certain that you have not explained that this could be avoided, that they can and should grind multiple characters at the same time (with the new OP guild system it's easy to be able to see glimmers and flots 1-2 day of the gameplay). That the chance of their base getting sieged is quite slim as long as they maintain a friendly relationship with everyone + the chance of some faction coming to help is good (if you maintain trade relationships) and so on.
