No on is against having more Yen and Triss but the game is not the book. The game should have been evenly distributed allowing the gamer to decide. Our biggest issue is that the game is skewed toward Yen. If you go with Yen everyone is ok with that decision. If you go with Triss no one acknowledge your decision/choice or your relationship. Not even Yen. It's disturbing.
The game isn't skewed towards Yen. It is in fact quite the opposite. Everyone keeps meddling with Geralt's personal life, telling him how bad Yen is and how good Triss would be for him. As a Yen-romancer, it's quite fucking annoying. I want to tell all those NPCs to fuck off and mind their own business.
I know how CDPR handled the Yen romance makes sense and also happened in the books, but I do think CDPR went a bit overboard with the amount of Yen-bashing by the other characters in TW3.
Another reason I don't believe the game is skewed to Yen is the fact that the amount of romance content is near equal between Yen and Triss. The only reason we see Yennefer more often than Triss is because she's more important to the plot of TW3 and she plays a more central role in the game. But if you purely look at romance content alone, Triss and Yen are pretty equal.
Sure, Yen got 1 extra sex scene, big whoop, Triss already had a way longer and more detailed sex scene in TW2 so I'd say things are pretty equal in that regard as well.
