As sad as that fact is, sandboxying 4 windows on 4 bare minimum 175 OD characters eternally WM walking is the fastest way to acquire the best items in the game.
Sad fact is people are trying to farm things like special encounters. Desperate hunger of items replaced common sense and killed the joy.
Yeah I know what you mean, but the whole "nolifer" argument just doesn't apply, sometimes people just have time to try it, or go out of their way to do it.
If there is a way, even if it is the slimmest damn chance, of finding "rare" items (items that cannot be crafted, found in common locations or bought from vendors), people will try for it, I mean the rewards are so fucking huge, why wouldn't they? Then after a while, people find the "fastest" or one of the fastest methods of "farming" such a % chance and that becomes the standard.
That is just part of meta-gaming in general, you can't expect people not to utilise the "best" methods of doing stuff, and you can't expect people not to communicate with eachother.
What creators can do is limit and control those "best methods" whatever they may be, for the example of the SE "farming" method mentioned above, the most obvious solution would be to remove the rare item spawn chance from SEs entirely, sure that creates problems of its own, but they can be fixed in other ways.
From experience, and I travel around the map often, the only SE i have encountered while playing on my main was a nuka truck. It wasn't until I made a specific character to hunt SEs and spent hours walking the map before I found any SE of value... I don't think that is an effective way of stopping the flow of rares, it certainly slowed the flow, but if you take a look these days, there is no lack of PA floating around and some people have dozens of implants to themself.
