Bearing in mind that I've only touched AST for a couple of days, for some reason sleeve draw wasn't my main concern.

Main issue has been that the new cards are just no fun. It didn't matter if we used to fish balance spread, I can't remember specifically but iirc you couldn't drop your cards twice in a row without incurring a loss so even in times of bad rng you should've been playing other cards (single balance/arrow, etc.). On top of that you had ewer and bole that had some usage. Even if you only used those anecdotally, the fact that you had the option at all really gave depth to the mechanic and a sense of accomplishment when you used them well. This was all lost and I'm still fishing just as often to boot. Not only that but the AST lore was significantly effed over in the process.

The other issue I have is that noct really lacks an ogcd direct healing skill. I feel like at the very least Neutral sect should just switch your sect completely and not only affect your gcds.
