you could argue it was the selling point. First two cinematic trailers was just world pvp promotional material. Come be an elf, fight an orc. Or a dwarf, fight a tauren.
the game was pretty straight forward. it’s an open world with factions, they’re at war. you can pick a side but you’re now at war, too.
It’s a narrative choice to have pvp sidelined. BFA really dropped the ball by doing a twist where “actually we’re fighting for the future of azeroth, not for control of it.” while bringing everyone in the door with pretense of an all out faction war at launch.
Players should want to kill the other faction. Preaching peace is antithetical for the setting of warcraft. If they do that there needs to be some kind of plot point where conflict drives a wedge and the cycle continues. Still waiting on that wedge.
