It would be great if we could do something about the amount of small, not-so-serious clans. Increasing the cost and QI restriction will do the system well, is what I believe. Maybe a ~3:rd dan QI limit in addition to the 10-20k you already have to pay.
You might think 3:rd dan is unreasonable, but having a high limit is just how it has to work. If we restrict the amount of players who can make a clan, we're decreasing the amount of unofficial clans. Do that and more people will join the different clans, there will be less inactive clans.
For those who want to play in a group without the nessecary requirements, we will add "teams", which would work as our usual groups with no actual 'forum' or tag. No requirements, no cost, no visuals.
