Will nerfed cards that see no play get reverted?

Hi, i did not know where to head with this question, so i decided to ask support. Why does Blizzard not revert cards like Mr. Smite, Shadowcaster Scabbs or text on the wildpaw gnoll card? Only one of these three cards see competitive play (Scabbs). Reverting text on wildpaw gnoll, for example, would make Maestra rogue archetype playable again, which could affect current meta in a good way (as rogue only has like 3 playable archeetypes right now). And there are a lot of other examples of cards not being reverted, even though they see no competitive (sometimes even fun) play. Reverting this cards also could increase sells of old minisets as an advantage for the company and also would make wild format more fun for players.
