If the only reason to start a "tournament" world is to satisfy those of us who just want to watch it burn, then I would reject that idea.
Personally, I started a country on FB to get access to it's unique resources and, while I have been furiously trying to expand my economy to at least be able to defend myself against the big boys, I find that currently (at the time of this post) I am sitting at rank 12 with a war level 0 country and the possibility to collect some juicy GC rewards if I keep it up.
It's just my opinion, but I don't think it's fair to judge presidents on the war world the same way you do on the other worlds. The only incentive to live on FB should be war, not unique resources or GC rewards for best indexes.
