I have seen a couple ways to compete in the threads and I had an idea that might be fun play.

The Taskforce has an island and all the players in the TF contribute to upgrading it...in essence, the resource not used by lvl 65 and even those when smaller players are maxed and don't want to get raided, they can upgrade this massive island. Think like Forlorn hope.

Then, these islands can be attacked by other forces, leading to a new set of rankings and "best of the forces".

You would have to massively build out reporting...to know who is contributing, in what manner and maybe you could fix the regular force stats to include when people joined, how many Force Points they contributed...things like that. On this front the Mobile UI might not support more data, but maybe leaders can go onto Boom Beach and down load excel stats with their Boom Beach player ID and a temporary password.

You would need to install Leader to Leader chat, so that private conversations can be had...a long pain point. Perhaps Leader Notes like (Warned bob to get rid of Green statue within 1 week) so that we are not keeping notes outside the force.

As people come and go from forces, Brand Building happens, so TaskForceA gets known as a bunch tough guys.

In essence, surplus resources get used, maxed players have a wider focus, you get team building and sharing. You get to see other teams creative attacks. boom gets to redeploy things in a new way

Ok, blow this idea up, internet?
