First of all, clans should not be removed.
And the current adminstrative influence in clans are pointless, try to contact Sr. Staff about a clan issue, you barely even get a reply, I get they have a lot on their mind. Therefore it needs to be done differently I will explain why and why in this post.
EU and US have clan leaderboards, thanks to Soul there are great guidelines of what not to do and what to do in clanwars/clanbattles.
I think there should be a clan commision for every region, people who are experienced in clans and they don't necessairely have to be staff. People who are fair and make rightful decisions borg clans will have to deal with.
To be part of the clan commision you'll have to go through an Application and interview, obviously adjusted to the needs of the clan commision.
The Sr. Staff and clan commision will decide on major issues together and the Sr. Staff will set up the Clan commision together with the head of the clan commision, from there on The Clan commision can make decisions in every region, the rules will be adjusted to the needs of every region.
The Clan Commision can now run independently from the Sr. Staff (keep in mind there is a proces and they will be trusted). Now The Adminstrative staff can go back to what they dis before and haven't to bother about clans all that much anymore.
