I'd love to play Gwent regularly and see devs act on issues faster. Surely, we're all excited for new cards, it's great to expand on our possibilities. Problem is, expansions with overpowered cards aren't adding variety to the meta, but almost always limit meta down to few decks, doing the opposite. Meta in Gwent does not have to shift that much, it should barely change if at all, since Gwent is quite old and there are hundreds of strategies to expand upon. New cards should add some varnish to already balanced strategies, not completely change the meta, turning really powerful strategies into average mashups.
You're saying game is full of strategies - while that's true, people are just not using them, but are rather sticking to netdecking, mostly due to cards being too strong upon release every time. Unfortunately, acting on those problems often takes too much time. Times of Viy or SK Second Wind are probably my worst memories, quickly overshadowed by current events.
Gwent lost it's core structure. Game is favoring you due to random fact of being first, or 8/9P neutrals playing regularly in almost every deck for around or over 20 points, without any setup - that is certainly not the game we all fell for. Some strategies are non exsistent anymore. Card advantage doesn't matter, no deck wants to be on Red and early pass is an instant defeat.
In any case, I'm not planning on coming back until this is changed. I'm sure it will, I just don't understand why it has to take so much time.
Instead of sensible introduction and quick hotfix, we're just forced to live with it and play what everyone else does, cause it's simply stronger by design. So much changed because of few cards, and that shows it was not a good release. I really don't get that approach.
