The ability to gift gems.
As a clan leader of two years, I often struggled early on to grow my clan and increase donations. After years of experience I realized no one wants to join the clan of a lower level, or listen to him. People join a clan for frequent donations or high level troops. Even at level 130, I find it difficult to motivate people to donate troops because Clan leaders lack the ability to effectively incentivize members. Currently there are only a few ways to incentivize clan members.
Positive reinforcement:
Promote
Gratitude and appreciation
Reciprocate
Gems
Negative Reinforcement:
Demote
Boot
This idea would open a gateway of possibilities. Clan leaders could also safely gift gems to players during Christmas to boost morale and clan unity. This would not only expand player spending on gems, but players would better be able to incorporate our culture into Clash of Clans. There is a requirement that the gifting player must have 5 builders huts and may not gift achievement gems. Thoughts?
