Alchemy needs to stay out of Historic
No one who plays Historic wants the nerfed cards Alchemy is bringing. Keep Historic as it is, with Alchemy as its own format. Otherwise me and my dollars are going elsewhere. We get that you're trying to be Hearthstone, but when you "rebalance" existing cards that have already been printed as such and then tell me I have to use them in my existing Historic decks, we have a problem.
KEEP REBALANCING OUT OF HISTORIC. IF YOU NEED TO BAN A CARD, FINE. BUT IT SHOULD NEVER BE TWEAKED.
This isn't that hard. Historic was fine. If you need to make another Hearthstone, fine, but you won't be taking my favorite format away to do it.
Get your heads screwed on straight. What an abysmal idea. Rebalancing cards in an eternal format. Absurd. This idea is bad and you should feel bad for having it.
