I dont understand one thing - why does it mean it is better player, why doesnt it mean that NG is overpowered?
Because NG currently has the weakest bronzes in the game, locks bricks against deploy abilities/ pointslam, poison can be worked around easily ( defender, veil, purify, forcing low point targets ), no points/requires a lot of setup.
NG has like 4-5 very good golds, can't deny that, but that's it.
What NR decks are you playing? Triple duel shieldwall? Revenant control? SK patricide fury? Lippy? MO OH? These are all brainded decks where it's just a matter of playing cards, often without even looking at the sequencing.
So yeah, if that person can work around your meta decks with NG at higher ranks props to him, good piloting skill ( or luck ).
In short: you having trouble beating NG definitely does not equal to NG being overpowered. Especially not while playing as a NR or SK player.
Sorry guys but all this sounds like BS. Just played as usual vs Nilfgaard, I get those like 8 out of 10. You keep telling me it doesnt mean anything, I keep telling you that is becuase they are OP and most of the players go for easy win. So they Poisoned 4 cards, destroyed one with destroy unit with status, locked and stole another and then renewed leaders abilty to lock another. It left me with 3 cards or so. Now please, I am seriously curious, if you beat NG like anytime you please, becuase that is how you make it sound, how exactly do you fight this.
unfortunately there's no good news here. NG lost double ball so quite a few of the players went to SK/NR, as is evident by the huge drop in play rates for NG and the increase in SK/NR. It's not that NG is bad it's still very strong but it's played less because it's no longer the "easiest" win, and that also means it's no longer encountered as much by some players. You will encounter NG players based on your deck (ppl here contest that but it's a far gone conclusion by numerous players). There are likely specific cards that you have auto included that is triggering matching algorithm. Change your deck and you'll encounter more of other factions. There's really no advice that hasn't already been shared to counter it besides another meta deck, that's just the state of the game presently.
I'd add that it has been the state of nearly every CCG at some point on competitive level, nothing strictly Gwent specific. I had my time in a couple more similar games (being a high-legend Hearthstone player myself for years before starting Gwent), and I can safely assure you that such binary states have been part of all these card games I've known.
First, and I believe this is the most important part to digest: you cannot and should not be able to competitively beat all sort of decks with your selection. This is normal, and should be the standard. You probably missed the party where SK dominated this meta for mulitple months after the previous expansion's release - and believe me, it was anyhting but fun. Or the days where there were significantly less options to fight NG poisons / Double Ball strategies (the latter never being the top-dog). Playing NR SW, you should face serious difficulties vs a Ball deck. Playing NR Revenants, not so much. The same goes for the classic SK warriors package - it should be a solid matchup vs NG, pretty even grounds.
To look at it from a different angle: the same NG poison deck suffers greatly vs a Fireswarm (non-devotion version) or a Lippy deck with zero tall units or important engines.
Yes, the matchmaking in these games most probably tracks your deck choice as well as your card choice to some extent, and depending on your winrate, will match you against opponents with a higher chance against you once your winrate goes over a certain threshold. Again, this is nothing new, the same happens in other CCGs as well. This serves the purpose to flatten the curve at some point, but keep in mind: it still depends on the player is he/she gets those wins, or not. Pro players are there where they are for a reason: dedication time investment, grinding and eradicating those minor(?) mistakes other players still make in order to improve those chances.
