I was a potion guzzling freak in my games. I don't recall anyone saying potion hoarding was an issue. As others have mentioned, alchemy is closely tied to exploration and the size of the map. I strongly feel the new changes reflect that. It's open world now, we don't know how often we'll come across the right herbs, when to drink or abstain. There are snowy regions, maybe well be covering vast stretches of land with no herbs in sight. I think the open world changes everything. Still not sure I like any of the changes, just thinking out loud here.
