And when was it? Geralt into Eredin? Henselt promote? Play weather and set everything on the row to 1?
Also, a put Midwinter "create" debacle on community as well. People were constantly whining about how this game was predictable and were demanding more excitement and unpredictability, read rng...
Fine is subjective. So is good, bad, horrible, great or exciting. Personally, the game felt better in CB, despite the flaws, early OB, despite the flaws there, and has been steadily going down-hill. Homecoming, on the surface, sounds like a continuation of the trend. It doesn't sound much like returning the game to it's roots either. Obviously, this is still subjective and lacks proper information to claim with certainty.
For clarification, many changes to different aspects of the game were necessary. The issue isn't changing aspects of the game. The issue has been how they have changed them. In a general sense, the trend seems to have been to add flexibility, player freedom to both deck building and card play decisions, and increase the design space (give the developers more freedom in design). From my perspective, the way many of the changes were made to do so has also marginalized or outright removed much of the decision making going into when, where and how cards are played.
I'm not sure what you're getting at with putting blame on the "community". Developers make the game. Players give feedback. It's up to the developer to decide how they use feedback and, more importantly, how they address problematic areas of the game. Failure in either area does not rest on the players.
Adding RNG to the game isn't the only way to reduce predictability. Even if it did, predictability is a large component of the skill gap. It's not even particularly bad for the game to be predictable from a deck A vs deck B perspective. So long as the play by play and round by round isn't completely predictable and there is variability in the decision making process. In other words, knowing the opponent strategy is fine if they can still adjust their tactics to achieve it.
Going back to late CB and early OB.... At both points certain decks floated to the top, as they do in every meta once it has a chance to settle. At both points this is how the game play felt. I might see the exact same deck or build and get unique game play over the course of the game. As time has gone by this has felt like it's stopped being the case. Same deck/build, same game, lack of replay value. Not good for a CCG.
