Lol, impossible. No tribe can survive without diplomacy. Diplomacy is key. Even the rank #1 tribe needs some diplomacy. Sure, you can be restrictive, but having no diplomacy does not make you elite, it makes you incompetent.
By your classification therefore, there are no such things as elite tribes.
And on the topic of families, its just a stigma associated with them. Ppl feel threatened by the overwhelming numbers that a family possesses compared to a single tribe, hence why families are unpopular. Its not cause they are bad, its because (assuming the family functions as well as any good tribe) they are TOO good. If you have 10 equally skilled players versus 20 equally skilled players, who wins? The one with more numbers. Hence, families have an advantage. You've just got to filter the noobs out of a family though. And when I say noobs, I mean incompetent players, not ppl who are considered militarily weak (some of the best leaders in W14 had around 60K points only :icon_eek
