The SK-100 has become an integral part of the WoW scene over the past couple of years. Whether it's for article research, forum ranting or simple curiosity, the arena ranking tool has become the go-to resource for any serious arena player.

Ever wondered exactly when disc priests took over from holy paladins as the most successful PvP healer? Now you can find out at the click of a button. Now you can not only look at the most popular and successful comps of the moment but also the best setups of the game's history.

You can find the complete rankings right here.
