+1 to this..
when you talk about effort to make something happen, you become to think like a game dev rather then a game player(user). we are users, so think as a user. dev problems are for devs and we may never really know hard or easy will it be for them to handle those problems. user may only "assume" things about developing but not acctually "know". same applies for the dev side.
i think d3 has an awesome camera view, hit feel etc etc, and i guess pvp would feel very satisfying and unique if implemented well in it.
d2 had no dev supported deep pvp as you say, yeah, it was mostly created by community effort. but also when you think of it, this was a completely okay thing for its time. in 2017, we are far from that point now with internet/multiplayer being much more accessable. gaming is much more global and social. doing same thing today is not okay anymore. devs are responsible for those social interaction between players. its not something luxury anymore. its fundemental.
josh may have said those words, but it doesnt mean pvp discussion should be a closed case. after all its the users who play the game. this topic is alive as long as considerable number of players keep demanding and voicing opinions about it. as you see, its not forgotten, and if its not forgotten then its not dead.
pvp is not the reason why some games are crap. real reason is, the way how todays devs deliver it. its very wrong to cut everything in sake of pvp. so that "big fat no" is acctually not fat at all. if you are looking for whats wrong, then i advise you to look for details instead of existence of the pvp concept.
And yeah, why do we need to think as dev and not as a user??? LOL!! and why big FAT no? and also im not epeen braging about how good i am killing other players! i just like the game to have this kind of feature ( PS: im totally not good at PVP's and people normally call me loser in that regard )
