This video features the retadin/rogue 2v2 setup. All teams in the video are 2k+ rated. I've tried to include the most common setups but for example shaman/warrior and paladin/warrior aren't there due to them being fairly rare and our counter pretty much. We've beaten a few but sadly the best stuff never gets recorded.
No PvE raid gear was used to achieve the rating, and Xawe was actually using season 2 weapons up until 2,2k.
