Can we please shuffle the shards?

I have two GLs and have finally reached the point where I’m competitive in my arena; however, the group that runs the top of the arena is closed and actively targets anyone that reaches the top 20 to kick them out. It’s coordinated chain attacks. I don’t object to coordinated shard groups but when you’ve completely closed them and won’t allow anyone into even the top 20 this is getting ridiculous. Can we start shuffling the shards every few months to keep these exclusive clubs in check and make it so we don’t have the same people we are fighting every time.
