wow i was gonna add. But this is awesome idea! They dont even have to make wows arena where its the pinnacle of pvp rewards. Just bragging rights and im happy! companions i 1v1 sounds so awesome.
I know at least 2 wow players who would come back here for an arena. Wow has a huge arena fanbase. not the largest, but very big.
EDIT: also, wow never said they regret arena, but that how it was implimented, the game wasnt designed for it
