IMO it's the sticking together that won it. Five players sticking together will dominate CTF but there is little incentive for low dps to participate in that sort of thing. If it is 5v5 (and gear is equal, big if) then things get interesting. I hope they have a 5v5 deathmatch arena in the future. I think in that case 5 mages would be good, a good kiting mage group could get the other team's warriors overextended quickly (and then quickly die) and then pick off the others.
