Yes, I agree, I may be confusing job balance and scaled content as contributing to the same problem. I was just thinking that smaller groups = less jobs that can go and still get the job done, less incentive to bring along someone for the clear or whatever, less and less shouts or events organized.
I understood part of Draylo's point to say that rewards are the same whether you take 6 or 18, so if 3 people and their mules can get the same drops why try to squeeze in 18 to fight over the same lots.
