Hey, so Liran said that clan rewards for top 4-6 clans were going to be added in the qna video. That video was made months ago and still nothing has happened. Adding this feature is pretty easy and doesn't take long time at all to do. It's such little coding but it has a really big impact of the game.
Clan rewards for top 4-6 clans would encourage all the non top players to continue playing, keeping the community growing more and more.

I hope the new clan rewards will be added soon.
