PvP was ruined at patch 2.4, see this thread.
Why not bring back TC/IP mode where we can have our own way like LOD? Wasn’t D2R supposed to be a remake of LOD? Yet these devs make perplexing changes and leave things out that make no sense? You will bring back thousands of people just by adding in TC/IP. You had that in the alpha. Why take it out?

The largest reason is Digital Rights Management/Anti-piracy reasons… Hackers quicky sliced, diced, hacked and pirated the D2:R Technical Alpha in a very short period of time. However the tech Alpha was local single player only, as it had no network capabilities.
Blizzard wants people to buy their game. They knew that Diablo 2 is probably one of the most thoroughly studied and hacked games in existence, and they also knew that multiplayer is the most sought after mode of play, so they did whatever it takes to make sure that people who want to play their game get the game from them, and them only.
Another possible reason is potentially keeping hackers/botters/packet sniffers in the dark as far as any potentially updated client<->server netcode workings. Since hackers don’t have access to a “server”, they don’t know what is truly going on server side. They can guess using the client and network analysis tools/packet sniffers as a “mirror”, but they will never fully know.
Vicarious Visions took up the challenge…
Admirable.
I mean to be fair, they’ve already did that with D4… so… ehh. If there are p-servers of D4 out there, there really isn’t a huge argument to ignore TCP/IP D2R. 
Show me an example of DRM/anti-piracy measure that hasn’t been broken because it’s not technically possible. You sound like a Slashdot poster circa early 2000’s. All DRM/anti-piracy can be broken, it’s just a question of if the smart hackers want to invest the effort. This 20-year-old narrative needs to be retired. There is no reason to even bother mentioning it. There are other reasons, and this is not one of them.
