With SY, it seems there was too much emphasis on creating a faction-specific identity. This resulted in creating the coin mechanic as an uninteractable and faction-specific mechanic. This is a big missed opportunity to develop the already existing factions at the same time with this expansion. The game needs to be developed, balanced and grown as a whole, creating fun and interactive mechanics that make Gwent the best card game. Archetypes can be created within any faction, by having a specific group of cards with synergizing abilities and using (a combination of) specific mechanics. However, these abilities and mechanics should never become uninteractable for opponents as this makes the game less fun and on top of that, a balancing nightmare (like artifacts and Immune cards in a similar category).
Coins are very interesting and can actually replace the problematic charges. Coins could be used by multiple cards in all factions. Coins could add a fun complexity to the game if they are kept by units and can be stolen by the opponent, as proposed in the thread "Suggestion: The new and improved coins mechanic". Having a game-wide new mechanic will make the entire game more interesting instead of only the new faction and will make the new mechanic a lot easier to balance across factions.
