When I do BFF, I don’t only go bush to bush either. I harvest other nodes, kill mobs, etc. However in my experience the very few times I’ve seen a afker, they haven’t been taking up a significant number of the huge amount of mobs in that forest that it would cause me to complain about it. But I was specifically addressing your claim that “they make it more difficult, or in some cases, all but impossible for others to complete events or hearts”. I don’t know of a single case where that is actually true.
I’ve already cited the Prosperity Valley crystal race. The Inquest in that event scale up rapidly in response to the number of nearby player characters. That event went pear-shaped with disturbing regularity when people were AFK farming there.
Those farmers were truly AFK, too, using auto-loot to keep themselves from being disconnected after being idle for too long, so they didn’t disappear when the sandstorm started. That, in turn, meant they scaled up the Haze event, the dust mite twister event and the skritt burglar event when it spawned in that area, all of which became more difficult to complete successfully for the people who were actively trying to participate, and failed more than a few times when I was there.
More? Okay.
Silverwastes – people parking themselves outside one of the camps, pet on aggro, heal on auto. When Mordrem attack the camps, they go down relatively rapidly, but with more than a couple of these AFKers in the area, the event scales up, to such a degree that forces have to be pulled from other camps in order to prevent failure. If it’s not an organized map, the camp falls, and when someone comes along to retake the camp later, they’re fighting scaled up Mordrem from the outset because the farmers haven’t moved (the game doesn’t care if they’re dead or alive, active or AFK, only that they’re present, scaling up NPCs accordingly. that’s why people yell about others lying around dead at Tequatl, or the wyvern bosses in Draconis Mons).
Plains of Ashford – skale, Separatists and ghosts are all popular farmer targets, and all necessary for heart completion in their respective areas.
Iron Marches – ghost farm in the southeast.
Google will find you many more examples of AFK farmers causing problems like event failures and difficulty completing hearts. If you haven’t experienced these types of situations, that’s fantastic. I envy your good fortune. And I’m not saying, suggesting or implying that it’s a game-wide end of the world cataclysm, only that these things do happen. I have experienced event failures, I have had to walk away from hearts in different maps on more than a couple of occasions and I know others have as well, both from personal exchanges with those affected and through further research before adding my two bits to this discussion.
I have frequently done the Noran’s heart without touching a single centaur at the centaur camp. But if I preferred killing centaurs there to the other things you can do to complete the heart, I would tag centaurs before they were killed by the engis. After all, there are many engis there and yet the kills aren’t monopolized by only 1 player. So the other engis must also be getting tags in.
It wasn’t a matter of tagging every NPC in sight for the engineers, it was simply tagging enough enemies to make it profitable. There were so many turrets that they could take down every centaur which spawned, clean out the entire basin, in seconds, and they weren’t all focus-firing on one enemy at a time, the turrets were spreading out their field of fire, taking down all of the standard enemies at once. Veterans lasted a little longer, long enough for non-engineers to get a tag in, maybe even deal a few K damage, but they also spawned less frequently, even with the large number of players in the area. I suspect the entire centaur camp was set up to bypass the scaling mechanics, so the basin area could be used by loners or characters with lower attack strength, so they could at least get a taste of what the “leather farm” was supposed to be like without having to join a zerg.
Prosperity Valley blah blah blah
I have never seen a farmer there. You say it “was a favorite camping spot for farmers for several months” – why only for several months? If it was a favorite, why would they stop?
The auto-loot mastery introduced with the expansion was preventing players from being auto-kicked due to excessive idling. That was fixed.
