Please make it possible for clanleaders to set up some requirements for joining the clan (similar to the game requirements like lvl or bootrate)!
Please do not treat WZ Idle and WZ players equally. Or at least let the leader choose if WZ Idle (only) players are allowed to join.
Maybe this is what Fizzer's cryptic "Coming soon" post is about? Hoops to jump through before you can join a clan?
Either way, this is also my conclusion from opening up Optimum and Prime. Most of the managerial work in those clans is with kicking out confused Idlers who accidentally join.
