Agreed, it’s like pulling teeth trying to get Blizzards Arena frames to go away without 3rd party addons. If Blizzard added more customization to their arena frames we wouldn’t have this problem. The need for 3rd party addons is often cited as a barrier to entry by aspiring PvP players and a disincentive by PvE players that might be PvP curious.
I’ve taken the time to compile this list of feedback and issues with the current state of PvP in an attempt to have them addressed, if anyone is interested in checking it out, I’ll leave it here.
