The only difference between the PvP server and the PvE server is population. Otherwise it is the exact same server, sans raid progression.
With that being said, I can see how some would not see it as blizz-like as retail servers are capped at 2500. With three times more players that means there are three times more questers and gankers. Questing kind of evens out the higher you go, but the fact people cried out for a PvE server to get away from the merciless world PvP speaks volumes. Once you hit STV and tried to quest to get through that range, it was obvious that no retail server was ever that bad. Even going to Desolace or South shore proved too difficult to quest efficiently. I personally rode gnomer and SM runs just to brave the storm. Some people aren't fortunate enough to play often and long enough each session to rely on instancing.
I admit the high population was an incentive at first, but I can now see how some would see it as a bit too over the top. Thanks for the Blizz-like cap on the PvE server!
