When leading a tribe, you often have to sacrifice part of the game. Some will play more defensively to help protect players, I also work as a nuker and prenobler for the tribe. My nobling history since I became a leader is pretty poor, but consider this, if someone gifted you villages you'd take them. I've had 5 players leave and wish to gift me ALL of their villages, and I've never once taken them all. Part of leadership is that your growth will be stunted in wars (if you play the style Zaria does) and therefore you will have a poor OD for your points that you gain from gifts.
If you look at me, I'm presently merging accounts with my new co-player, who is an awesome player. Those who know me from other worlds know I normally have an OD rank 3x better than my points... and those people mail me laughing because they know how upset I am... But I have lots of nukes spare... I'm thinking of attacking Thaddeus just to gain some!
