Wonder how come this was not added before. Right now, after MP battle, it just dump you to the reward and back to the lobby. Why not still have a little chat window after the fight to still chat with that player after the fight? Now one reason I could see is that it might promote too much of flaming or grieffing. But than could also ignore them, close it and jump it to the lobby, and report if they have some bad conduct. Could even add some possible future new features here too, like item/weapon show case (you can see your opponent's team build), player stats/profile look up, add to friend/rival list, trading(?), watch/save Replay(?), etc. What do you think?
I'm sure they did this by design. The chat window is disabled immediately at the point of no return, when the animation for the final game winning action starts playing. They don't want people yelling out swear words or expletives at the other player.
But then again we don't have a chance to gg each other. I'd rather have that instead. See the game actually resolved and remaining hand revealed. Then I can chose to quit and claim my chest whenever i want.
This would be nice. Give the players a place to talk at the end of a match, but give the players the option to leave the lobby if the other player starts raging.
