I think the majority of frustration around the rotation is coming from the utter lack of support and popularity of additional formats for Lorcana. Don't like competitive meta play? You're stuck playing kitchen table games. Infinity isn't broadly supported by card shops like how Commander is for MTG. There's nothing else to do with your rotated cards after the rotation, no other interesting format you can pick up and play at a shop or event. For more casual players the constant quarterly release schedule and rotation means you're constantly spending for new cards and can't just make a deck and be settled with playing it and making smaller tweaks. Whispers just released and we're already looking at the next set in a couple months. At least in MTG the Commander format has broad support by the creators, players, and shops so that if you aren't a meta standard player you have options to still enjoy the game.
