Everything can be killed with 8 people or less. SE has said in interviews that this change will be coming. Even if you hadn't read the interviews this change should have been hinted at by the skill point and experience point return from having more than 8 people in a group.
Anyways I am curious about the attribute bonuses they will be offering with "light parties" and "full parties."
EDIT: On a side note if people are really upset about this change, larger linkshells can now have two groups to take down NM's and such. If anything larger linkshells will have an upper hand in this situation.
