I actually like playing Wild so I think that proposal is silly and bad. I would like for them to actually consider Wild as a viable format (though based on how they have historically treated arena, I'm not too hopefuly of that), and thus not just dump broken shit all over it.
Face/Aggro Hunter might be the strongest deck in Wild atm. Secret Paladin is still good of course, but with Small Time, Patches, and Glaivezooka being insane together it can win games faster than Standard Pirate Warrior and also it hits so hard that Secret Pally's insane curve doesn't help it enough. Aggro Hunter in Wild is pretty nuts and it barely relies on any of the usual Wild suspects (it has Mad Scientist tho, cause that card is still OP).
I think N'Zoth and cards like it are nods to Wild in general so Blizzard is at least thinking about it in a small way. So I hope they keep it that way.
IF they are going to change cards, they might as well just keep them the same between formats. No reason to make multiple versions of a card when every other CCG I can thnk of doesn't do that either. Errata happen, and all copies of cards are assumed to be latest wording regardless of what gets printed. I get that this is digital and they should be able to break conventions like that, but in this case I don't see a benefit. If they card is detrimental enough to ruin the game completely it should be dealt with across all formats. I'm not convinced patches is there yet given how good Reno decks in general are currently performing. If aggro was that overwhelmingly powerful, those decks should just get destroyed. Strong aggro cards don't need a nerf just because they are strong.
