I know, I know… Nilfgaard is ruining the game and is the root of all evil in the world, etc.
I'll probably get downvoted to oblivion, but if I can change one person's mind on this, then it's probably worth it.
Nilfgaard has been my favorite faction since closed beta. I love the play style because it's similar to the rogue class in Hearthstone and a lot of decks I like to play in MTG. Even if it were the worst faction, I would still play it. Also, I play and enjoy all other factions. I imagine other Nilfgaard players have a similar perspective, or maybe they are simply achievement hunting or trying out a new deck.
The "GG" system is intended to reward your opponent when they are a considerate player/good sport. I take this to mean not abusing emotes, not unnecessarily taking more time than needed on a turn, and not showboating/playing extra cards at the end of a game after their opponent has passed and they already have the win.
Why punish someone for playing a deck or faction they love when they are otherwise a considerate player? The devs designed Nilfgaard; don't blame they player who likes to play it. It costs you nothing to send a "GG."
Like I said, I'm sure most people will have a problem with this "hot take" and downvote or mock me, but I felt compelled to share my opinion either way.
