Amen, and thankfully I don't think it's as widespread a disease in the game as it looks out here among fansites and forums.
I personally am surrounded by people that either a) Hate having "new talents to pick" or b) Are "good enough is good enough" oriented and will 100% pick for concept and aesthetics and will never switch. Like I mean never switch conduits or soulbinds either.
There is a shelf where covenant minutiae will matter but it's not intended for most players, and not intended to be PUG'ed. Blizzard can't and shouldn't address "waaah I'm not FOTM and no one will pick me" because that's a community issue, and letting that toxic element of people "playing where they shouldn't" (PUGing upper level PVE content) drive their development is a game that can't be won. They CAN win the game of curating the difficulties intended for strangers to play together: The queued ones.
ACTUAL upper end players will make the covenant system work. The people that think they belong on that shelf can either do the work or look in a mirror. At that point they can join those of us with reasonable goals who are enjoying ourselves, or quit.
