Suggestion for adding spectating function to Arena card pick

Hey, I have really been enjoying playing arena myself and spectating friends’ arena games. However, it is always frustrating while friends’ card draft phase as I can’t spectate it and sometimes we have to use video calls to discuss and then switch back to voice calls after it. As an essential part of hearthstone arena that offers no less fun, or even more, than the real playing phase, card draft is very enjoyable to discuss with friends on which card to pick, and I don’t see why can’t we add the spectating mode to it, which is very easy to do and would add a ton of fun to the game. So please do that, so more arena players can enjoy the game more. thnx
