Lack Of Battle-Ladders

Is there any reason we decide to rank clans purely off popular opinions instead of doing something like an official battle ladder with some rules? I dunno it just strikes me as odd that we don't actually have an official ranking system for our clans despite the obvious competitive air that our current clans have. Could also use said battle ladder to appeal to people not familiar to the clan world. I dunno was just wondering was all.

Also If any of you guys have an idea of how you think a battle ladder would work, post your ideas.
