PvP in WoW went from honourable combat of not attacking those at quest givers to “LOL I killed you and inconvenienced you for 5 minutes” then “HAHA I killed you again” all the way in late Vanilla - early TBC. It’s got worse in WoW and in nearly every online environment for me since then. World PvP can be mildly entertaining, but the trade off is getting repeatedly ganked, spending inordinate amounts of time in the spirit world, and being annoyed at the game.
