I’m not sure what the goal of opening tickets are, but when you state
The problem here is gm staff do not play a part in development of the games, and it’s not just wow that is supported either, but all games under Blizzard.
If you find something that might be a bug, or have a game change suggestion, there is a way in game to send this directly to development, and not have to wait for a ticket.
I hate to say it, but ultimately putting in tickets for things gm staff can’t help with, ultimately raises the wait time for things they can.
Perhaps this thread might help understand.
