Ahoum... does this mean the demigods are locked to one side? Does it mean I can only fight with 4 of the demigods in a tournament?
For the tournaments, off the top of my head I'd love to see
1. Top contributors for each side, as well as ladders
2. Fun statistics like total amount of grunts killed, text messages typed, spent money ratio on items/citadel upgrades, average time until victory
3. Rewards for winning tournaments that aren't favor points (hah!)
Clans/empires might be a good idea, expand on the idea of light and darkness, imagine a larger amount of sides (empires) fighting for domination. Empires consist of clans, obviously. Like a ladder but for the group effort.
One thing that's been mentioned before is customizability on the demigods. With only 8 models and no item variation and very few things to alter their appearances, it could be a golden opportunity to connect that need with banners for empires, or item decoration for winning tournaments.
Edit: Once the game becomes more balanced, it might be a good idea to reward underdog sides in tournaments with more xp gain for example. People tend to choose whatever side is winning (assuming we have to choose?) and that would result in too many on one side which means people have to wait for games (zzz).
Edit2: I think with the tournaments and everything moving a bit to include "mmo" features, it will be necessary to have "whois" information about players, that could include ladder status, games played, current side in tournament, total favor earned, achievements, a person's email should he choose, a square where the player can input whatever he wants to. Coupled with this, of course, chat systems and friends lists.
Edit3: Judging by the screenshots, whatever side gets enough favour points wins. I think this is a bad idea. It should be a zero-sum game, where if I win, the enemy also loses something. In a zero-sum tournament, the closer I am to defeat, the more important it is that I win. If it is not zero-sum, then even winning is not enough at some point and I will not even bother playing as I know there's nothing to gain. A zero-sum game is never over until one side has lost. If it is not zero-sum, the game ends long before that. Zero-sum encourages competition. Other types just encourage apathy.
