This all day long; CDPR really do seem quite dim when it comes to applying changes.
The problem wasn't the Witcher trio - the problem was that they were the ONLY deck thinning card for 4 out of 5 factions. And because of the smaller hand size from Beta they were auto-include if you wanted any kind of strategic control over your deck.
Now it's win/lose 100% based on the deal. I can see it happen to opponents too, it's a two way street, but it's very flawed.
Hold on, do you really mean to say that people who didn't run Witcher trio have no skill at all. I got all way to pro and never used the trio until rank seven and then dropped it in rank 3 when I changed decks.
Thinning is important, but it does not change the skills required to win at a decent rate.
1. Smart planning. You need to know how to use what you have to get the max possible value.
2. Knowing when to pass. Blue coin or red, this is essential.
3. Knowing when to bleed round 2. Even if you take a card disadvantage, sometimes this is the right move.
I could go on, but the point is simple. The reason the trio got nerfed is that they are bad for the game. Same with unicorn duo, if it is auto include then variety suffers. You still have faction based deck thinning, and honestly you have enough value cards and finishers available you shouldn't need consistent deck thinning to win.
