No. Same stupidity - Rematch and it can be a mini tournament between two people. Who the heck gets angry playing a video game other than 11 year olds?!
Streamers who are the very same people that most of the player-base watches for Hearthstone gameplay. People enjoy seeing other people get angry like an 11 year old, but this feature will never get implemented under the name "Hostility" considering they removed the Sorry emote because it was triggering. Like I said before, Blizzard don't want to make many references to Diablo lol
What will this achieve? If you can't send a couple of [email protected]#$% their way what will this achieve? He bm's me and I beat him in casual game? Sorry but I won't feel any better. The only way I'll feel any better is if I totally crush him and we know this won't happen unless he gets a brain fart and ques with basic deck or I'll manage to get some sort of perfect counter, else it's a possibility that hostility can turn into hatred that will ultimatelly lead to suffering and will not achieve anything.
