And who elected/selected the people in charge of such changes? Was the community (every active player) asked, as a whole, if they actually WANTED a group to do this (and knowing what they would do)? Or just a poll in a forum from which some (or all) might not be an active member? If the idea is to "go with the flow because, if no one does, no one will do it", I'm wholeheartly against it, I don't think such a comitee should have a say in how I play my cards, they're not the authority on the game, they do not have the authorization to be, and errata, as has been mentioned, is extremely confusing.
Adding new cards? Sure, that could work, I could simply choose not to play with those cards. Having a format where those cards saw errata (assuming anyone would even want to play them after errata)? Sure again, go for it!
FORCING a format upon everyone where we have to remember erratas and abide by changes made by a "comitee" that was NOT lawfuly instituted for such and is not taking the whole pool of cards into consideration before issuing errata to see if they make something even more degenerate? Not a fan. Not at all.
I applaud the effort, but this is not the way, this is the way dictators rise to power and stay there: "since no one will govern this country like it should be governed, I will!".
