The Social Aspect
I have heard the rumblings in the forums about social communication in Gwent. Not only round-for-round communication, but also for things like Guilds/clans.
The beta has seemed to focus mainly on gameplay and balance, but i do think there is a lot of potential for interaction either in between rounds, or just with a real time chat box (que the active trolls). And I realize we have steam chat and other social media sites, but this COULD possibly take out the "faceless opponent" stigma out of the round. Possibly have pre-set responses like rocket league? (Golly!, nice kill!, sweet meta bro, good game!, that could have gone better for you, etc). Those presets could have vernacular from the denizens of witcher 3 hild hunt as well. (Sod off, ploughin' great, etc)
Something else a little related that I would like to bring up is potential for social media sharing. Either screencap or video. I realize this is all possible through xboxone and steam screencap programs, but having a in-game share button right after battle could be fun! Maybe with options to record the entire game much like rocket league. With watermarks wherever in the timeline you pressed "record".
Just a thought. I know the closes beta is to balance the game, which is why this is in general discussion.
Maybe my approach here is a little unfounded, but I personally would like to see the social aspect of this game blossom.
