There is a thread for this.
It is explained in the very first post.
What each players desired outcome is exactly differs from player to player. Some people want power completely stripped from Covenants and put into our character. Some people would be happy purely if the Betrayer system was removed (so you could switch freely, but have to level each Covenant individually).
But the general “ripcord” is Blizzards unspecified Plan B incase Covenants have failed, which in many players eyes (including myself), it has.
