Well, but in this case the point of the CDPR staff is legitimate, you can just use you in-game GoG chat for that if you play with friends.Having free text chat only in friend matches might be a good solution, while keeping the random matches chat free (or only emotes/fixed text like GGs, etc.)
Not sure if that would be a great thing, played some online games where All chat was a thing and the ammount of toxicity came out of it was absurd! Even in Hearthstone people adds you just to harras you for no reason at all! Taunts and Jokes from your heroes would be a thing i'd like to see in the game other than that would not work! The ammount of sarcasm and mocking that could come out from some Leaders would be hilarous or maybe some Leader - Legendary card interaction would be awesome as hell as long as it wouldn't hold up the gameplay!I'd actually like to say and hear mind-game stuff. It would be a good fit with the overall bluffing theme of Gwent.
I understand why CDPR won't go for it though.
