This sounds like an awesome idea to liven it up a bit but I see a flaw. Scenario: Team 1 has 3 people, then Team 2 has 10, how would you get them to go against each other in single without Team 1 being swamped? I mean think about it, thats 5v2, Team 1 would run out of food far before team 2 in singles, and multi wouldn't be a viable option either because that's just a massacre. My hotfix to this would set the max cap to a single team to 3 people, wouldn't really be a clan event at that point but would still be something I would consider joining up in! Also you could set tiers, so tier 1 is 3 people teams, 2 is 5, 3 is 10. Or whatever you'd like. Then have those teams pick 1 victor for a singles fight so numbers doesn't dictate a certain victory, just some ideas.
