I think it would be great if you guys added a sort of help bonus system for clicking the help button, maybe a special currency that can be redeemed for small prizes? It would encourage people in my clan to help each other with little boosts and incentives.
It's not hard to hit the help button. Teach the clan about reciprocity. They help people and people help them, it only takes a few seconds to hit help all. Being helpful leads to others being helpful too. It's like us buying pints...it may cost us 1k gems for just 100 energy...but when all the others in the clan do the same, it adds up quickly.
