Personal Team to do arena in Blackrock

This message is a suggestion that I thought. Don't know if it's the best option.

Introduction:
In BlackRock, to do arenas frequently need to find partners to do arenas 2x2, because SoloQ 3x3 can be tricky for some people and most of the time the gear matters. And to find players to do 2x2 arena, most of them have teams and don't want to change it due to farm better rating/points in own team.

The idea:
Similar it occurs in solo queue 3x3, why not make this system as only duo queue for 2x2 arenas. This way people can maintain its own arena team, points and claim higher ratings with flexibility to play with.
