Clan chest

I belive that clan chest is far the most useless chest as the contents are more or less the same no matter the level and the keys required is so high but the rewards are barely worth the time to get the keys, like i belive that the contents of the chest should get better as the chest lvl increases because its a clan chest and it only comes once every few days or even once a week so the contents should be worth the time and brew we spent on getting the keys.
