A lot of us have been there - we use the "Change Name" feature, but realize we don't like our new name. A solution? You could be able to buy another "Change Name" feature in the shop for 500 gems, but only once every two months to stop people from completely confusing their clanmates. This would allow people who are dissatisfied with their current name to buy a new name, increasing their happiness with the game. I'm pretty sure this has no loopholes, but if you have any more suggestions post them.
