So do I.
It’s a shame they replaced the ‘Sorry’ emote with a worse one, i.e. ‘Wow’, due to all those winers. I still recall that little interaction between Vaelastrasz and Malfurion you could do in BRM:
– The fury of Blackrock courses through my veins!
– Sorry about that.
No longer possible, though. 
(Sighs, tries to calm oneself a bit) There might be such a disorder, but not on the side you suspect.
The effort that your propose is apparently too great for this kind of… forum audience.
Why ever not? It’s a part of the game content, and I totally wanna see it!
By the way, this reminded me of another thing. Remember that ‘Tavish vs Rokara’ tavern brawl? The coolest thing about it was all the different interactions you could hear, yet instead you’d match into ‘power-players’ trying desperately to counter-pick your hero power or something. In a tavern brawl, come on! Okay, get your pack if you really want to, but how about having some fun in a game for a change? Now, that part is annoying, if you ask me.
And yeah, this angry bozo was talking about ‘good sportsmanship’ etc… Sometimes I’d try to play as many cards as possible, do as much face damage as possible or such to get rid of some pesky weekly or daily quest while at it (yeah, I know), and if anything’s ‘bad sportsmanship’, ‘BM’
or similar in this case — conceding is, since it’s a form of ‘griefing’, albeit a legal one in the game, and not emotes and so on.
