Add spectation mode for arena draft pls

Hey hearthstone dev team, could you please add spectation mode for arena draft. Sad to see after so long time, it is still not up. Watching and discussing arena draft with friends is so fun, and draft is arguably the most important phase of arena. And I suppose it would be too hard to add that mode right? So pls could you just add it and give more fun to arena players, thank you very much!
