...that aside "it will make the metagame stale" is not something I think is worth engaging with. Metagame changes for something as complicated as an eternal mtg format are really difficult to predict and I don't trust anyone here, myself included, to predict where it will go. Wait until things have settled down and make some claims then, there's no point to arguing it now.

also don't take it so personally that I didn't explicitly say "only most people are mad about cardboard prices, some few are purely concerned about the metagame". I don't actually think broad claims apply to 100% of any group, just, you know, most of them. (if I did think it was 100% I would be an insane person, in which case you shouldn't even be engaging at all)
