Like, I get it and agree that you need to nerf unexpectedly strong cards, but… can you say Entropic Gaze was unexpectedly strong? Can you say Enfeeble was? I dont see much alternative here, either some of these cards are not being playtested rightfully or the nerfs are planned beforehand.
Also, new expansion model is absolutely not new player friendly, because obtaining cards from a set in random order, even if 3x of, impedes quick enough deckbuilding. If a new player has a list of cards he wants out of the new expansion model, he faces a way higher paywall than would be a normal, core style orb set. Which is not exiting, and in turn, such a player gets more frustrated by playing, which in turn, may make them play less and less.
