Also is it impossible for Blizzard to say no? Apparently not, not everything with PvP needs to be an "esport" feature and that pathetic excuse doesn't deserve to be brought up in every argument you make. Get off esports, it has nothing to do with anything we are talking about ha. No way in what we are asking for is going to get people to go "WOW THIS WOULD BE FANTASTIC AS AN ESPORT!!".
Did you not read what I said? I was not saying it was an eSport feature. Go back and carefully reread link. I specifically stated that I used their stance on eSports AS A PARALLEL, to explain why they might have similar issues with these features. Not because these features are eSport related, but because these features would create an expectation that Blizzard obviously doesn't want (public world PvP).
I also wasn't stating these features SHOULDN'T be implemented. If you actually check the votes, I voted for both. I'm trying to explain why Blizzard still might not accept these kind of features.. and that is because they set a precedent.... they make hostility ok in private games, which opens the floodgates for people to say that it needs to be in public as well. Hostility in public is a terrible idea, and as such I can see why even private might not be accepted. That doesn't mean I am against private duels/hostility... it just means that I understand why it might be seen as a bad idea.
This suggestion is different. I don't like the whole mentality which states "we can't give the players something that *should* be in the game, just because it may give them the wrong idea and people will ask for more", to which the devs wouldn't even have to respond. I understand them not wanting d3 to be an esport, I agree with that notion, which is why I don't think the argument carries much weight seeing as how I agree in that d3 is at it's heart and sole a hack and slash (pvM) action rpg, and still want this change *because* it is only beneficial to the game in every single way imaginable.
I guess some people (and others are afraid that some people) just can't draw a much needed line. I think this topic is where the line should be drawn, personally I'd be happy for life concerning the state of pvp in d3.
You also seem to have taken my comments about eSports out of context. In addition to that, you state that open PvP "should" be in the game and I actually disagree with that. I am not against adding it but I don't think its a feature that NEEDS to be in Diablo 3 either. In fact, I think the majority of people wouldn't care at all if duels were arena only and hostility was gone for good.
That being said, I don't see a real reason to deny duels/hostility really besides this... It seems like a waste of resources as it is likely a feature that the majority of players wouldn't even use. As a developer myself, I'd certainly find it hard to justify adding a feature that the majority of my users wouldn't use. Its just not cost-effective, especially when nearly all the players demanding open-world PvP are going to pay for the game anyways.
