The current clan system encourages activity rather than skill and honestly I think that's a good thing. A lot of the top ranking clans right now aren't the most skill-full but they are definitely active, which is great. Instead of making a clan rank system a skill thing it should be made to be funnier, more interesting rewards etc.
Maybe staff could add "bonus" clan points for completing challenges throughout the week.
If a rank to determine skill is put out there then "player" rank should be priority, then clans.
