I'm not sure how tournaments have been going, but I'm fairly content with this. I don't think any changes should be made to the Vintage restricted list. There are still some cards that I think should leave the Legacy banned list, maybe not all at once, but at least one of the following should be unbanned in Legacy...
Mind over Matter
Land Tax
Worldgorger Dragon
MoMa isn't going to create any new decks that are competitive and it won't make High Tide dominate. It would probably be too expensive for High Tide. Land Tax would strengthen white-heavy control decks that are already underpowered compared to more blue-heavy control decks. But again, it wouldn't dominate and might not even shake the metagame up at all. Worldgorger Dragon would be the most dangerous because it could lead to a new (competitive) combo deck. But with no Entomb or Bazaar of Baghdad, the deck would probably be stuck with Intuition or Buried Alive, which is much less scary.
And I'm wondering if perhaps Time Vault should be banned as a precaution. I haven't heard of it winning any tournaments, but I'd rather have it thrown on the banned list without ever finding out (just like every other card that started out on the banned list for Legacy) than see tournaments dominated by decks containing multiple copies of a $60 card.
