The Swap update seems to be really bad.
The Runestone cards, Winch, Elven Scout, Wardancer, Vrihedd Vanguard and Slave Driver all seem to have lost their character and purpose.
The random cards due to the Create mechanic of the Runestone cards already made it a risky play. And now, with them showing Bronze cards as well, it has increased the card pool by a lot. Moreover, now I'm carrying a Silver card in my deck that might play out as a Bronze card. This is obviously unbalanced, and I won't be surprised if everyone starts removing the Runestone cards from their decks. Instead, a separate Silver unit card (with a certain Power value) should've been made for each Faction which could create a Bronze card.
Similarly, the Wardancer and Vrihedd Vanguard, and the Scoia'tael lost its unique ability of triggering Swap abilities during redraw phases. And this has made the Wardancer mostly useless. I would've worked on developing such unique abilities for each faction, instead of nerfing them. Removing the unique features of different cards and factions will make the game similar and boring.
Winch was a bit over-powered for being a Bronze card, but it was okay. It'd a Henselt deck based around it, similar to the NG deck based on Viper Witchers. But with its currently ability, I doubt anyone will be using it.
The Slave Driver was a relativaly over-powered card, but its unique ability has also been removed, now turning it into a varied copy of that Monster giant, removal card. It could've been changed into a Silver card instead.
This is probably the worst update in my opinion. CDPR must realise that changing and nerfing cards because players complain is a bad business model. The silver lining to this update is that I'm looking forward to the Homecoming update more desperately now. An overhaul and re-balancing is a necessity at this point.
