They don’t have to think about PvP as long as they keep trading scene fluent. Community will find a way to make PvP work as long as it’s practical and not an imbalanced mess due to power creep. The only thing they have to mind is NOT allowing quadrillion bloated numbers just like in D3 or adding special restrictions for you to duel one another.
They don’t have to scrap anything and mutual response PvP is not PK; get your terms straight. If you both agreed to duel and you lost, at least do it gracefully and don’t call your opponent a PKer.
If someone killed you on one sided hostility with a stat stacking, mass summon/absorb PvE build or hacked character, it wasn’t PvP it was PK. Getting killed to a hacked character as you turned a corner is not the fault of “PvP”, it’s the game’s infrastructure and it’s no more after well past two decades of coding under developer team’s belt.
PvP builds in D2 get to have restrictions due to imbalanced powers of most classes and they can not use certain skills as they have a BM (bad mannered) list too. It’s all community fueled to for a fit all model to keep people having fun. If you never played PvP in D2 or D1, please at least try not to be ridiculous.
With a casual match making system, it’s obvious nobody will have any PK options without mutual response; developers will not allow this to begin with. You’re thinking of worst, deeming developers thoughtless for even mentioning it, painting the design as culprit and trying to put the game into a mold without even seeing what it could’ve offer. PvP will help you to sell items much faster as people will try different PvP builds when they got bored.
If game will be an MMO-lite, it will have human interaction and some direct competition. Nothing is more natural than an MMORPG having trade and PvP. I have no idea why are you still complaining about it.
They can always make some PvP centric items gated behind crafted item systems while allowing a few BiS pieces, obviously kept in loot tables. You can have a crafted sword that offers more damage against nephilim, while having looted Harlequin’s Shako as helm for some PvP favoring affixes like block rate, you name it.
That depends on how large they would be; by logic these must be vast lands for avoidance or very small dead ends for people who really have to wander into.
Even if PvP areas clash with story mode flow in a few places, game has a waypoint system where you can avoid such areas. Previous installment completely separated brawl arena from the game, I don’t get this fear of PvP or this amount of presumption.
In a casual match making system a few players can simply wreck havoc and people will not have instant TP for PvE balance aspect, nor passworded name servers (duh!) like a decade ago. That’s the last thing developers wish upon the players.
One sided hostility most likely will not be an option already. If they allow it that’s a design flaw because game’s other features will not allow the victim to avoid it. However as they won’t allow it to begin with, it’s not severe or dramatic like most folks here make it out to be.
