In SWTOR, there was a similar thing where max level players from one faction would camp out near story objective areas of the other. Eventually, someone would go back to the fleet and call for help, you'd get the same counter-posse, they'd duke it out and it was a lot of fun...

...for the max level players participating in this. For my lower level self just trying to advance my storylines, getting barricaded was fucking awful. All I could do was sit there until hopefully some help arrived or the opponents would get bored. Or, of course, I could do something more fun with my time.

Like quitting the game and playing something that doesn't allow some assholes to stonewall my progress.

Yes, I could have started over on a PvE server or played a different character or looked for something else to do in game, but none of that fixes "I want to advance this character's story and can't because some people think shooting down defeneless noobs is fun".

They did eventually introduce a patch that capped your max level and equipment power based on a planet's intended level range (e.g. if the planet had quests in the 16-20 range, your level would get scaled down to 24) which made camping and killing noobs less viable and seemed to have fixed that (though I never really checked, I didn't play as much anymore by that point).

If the fun of assembling a counter attack gets sacrificed for the sake of that counter attack no longer being needed, that's a win in my book. People who enjoy PvP can play PvP matches (though idk if WoW has that) and the rest of us can deal with the occasional "encounter a hostile player and stare at each other, silently trying to determinr whether you'll both go your ways or whether you'll pull a proper FOR THE EMPIRE and hope they don't have any friends nearby that you didn't see".
