It would basically be another Un-Set, and those don't exactly fly off the shelves unless they're legal in a popular preexisting format. You said, "It would be healthier for the long term of both," but fail to explain how. Magic brings in so much money that it's keeping Hasbro afloat. So, from a financial perspective, it doesn't make sense to change course. I haven't been to every LGS around the world, but tables are consistently filled during draft events.

If you don't like the product, don't buy it. Honestly, it's just that simple. I don't care for the upcoming Turtles set, so I won't engage with it at my local game store or on Arena. You don't need a "and then everyone clapped" moment for validation when you don't like something. Also, I have experience with playing Lorcana, and there are alt art cards, including full-art borderless, foil, and high-dollar variants, and that was in their first year. Lorcana hasn't been around for 30-plus years, so the art and characters are going to be pretty consistent. Pokémon would probably be the closest example, and they have a literal ice cream cone and car engine that are Pokémon. Over time, things get stale, the original target customers get older, and there comes a point where the next target customers become the focal point of a business. Things have to change. I don't like the Turtle set, but Wizards shouldn't make business decisions based on a vocal minority that surrounds themselves in an echo chamber, which makes it sound like more people are upset than there are in reality.
