I don't know if this idea has been suggested or tried, so please bare with me.

I've noticed a lot of clans holding competitions for themselves, and then the thought occured to me: Why don't we have competitions against other clans? I thought this would be interesting and really give clans another big role. These competitions could be to see how much a clan has hunted, or how many fights they win in explore. They could even be to see who gets a specific mutie first! Rewards such as applicators or perhaps lion meat/ gmo cows could work, though this is purely up to the game designers. This would also need to be debated whether it's a prize given to the clan or indivual clan members, and then what it would be. If it was the clan, I'd maybe say a week feature, so they can get noticed, or perhaps something like payment for taxes for the next moth or so.
For individual players, I'd say it should depend on how much a player contributed and what place their clan was in. Top place clan members could get good rewards based on how much they've helped.

If this would be too complicated for a clan, then I think it could also work for individual players. Rewards would be easier that way.

To go along with this idea, I think it would be nice if clans could vote to enter it. I know not all clans are going to be interested in clan competitions, so why not give them a choice? I think a clan voting/poll interface would work for this, and would be really nice to hear feedback from your clan too! This interface can be used for competitions but also for things like raffles or clan-exclusive events.

If I've missed anything, made something unclear or you simply don't like the idea, let me know! If someone else has already mentioned this or it has been tried, let me know!
