Recently Played
We usually had a recently played area in our friend invites. We don’t get that for Battlegrounds anymore. This means we can no longer add new people we have faced against (or with).
Suggestion
I suggest reviving this idea, and maybe making it even better by allowing users to make their profile public (meaning their full BTag would show all the time), allowing people to add you if they wish. Potentially even adding a way to chat in BG lobbies.
Toxicity
I understand this feature may introduce behaviours like adding your opponent/temmate to offend them. Honestly, though, if they accept the invitation, where’s the harm in some friendly banter?
New Friends - Community
Hearthstone is experiencing a decline, at least in my experience. A big part of this, for me, is that it’s no longer fun to play without a good way to create new friends, build communities, and share experiences. We have plenty of other games where we have team/all chats, recently played, voice chats, etc. which can be used negatively but are overwhelmingly good for creating new bonds with people who also like playing the game.
Let’s face it, you’re not playing battlegrounds at 8pm due to your big list of IRL friends… I think this would positively impact Hearthstone in many ways. Giving us a way to add users we played with/against, and perhaps more features that allow chatting in lobbies, and creating bonds.
