Well this is secretive for one reason. The smart people keep the new-found information to themselves, because they know other people will ruin it.
For example, remember the pre patch dungeon satchel glitch? where you gather random dungeon satchels pre patch, and then open them after the patch and they would be a higher item level.
Well some people, like me, kept my mouth shut and only wanted twinks to know about it, farmed 80 satchels on all my twinks, and couldn't wait to open them up after the new patch hit.
Then other people, who are lazy/hateful/jealous, decided to rat us out, tell the GM's about it, and ruin it for all the rest of us.
And this is why noone says shit anymore.
Twinking is all about thinking outside the box, working harder then the next guy, or outsmarting him atleast.
Now we live in this socialist bracket where everything has to be fair, and equal, and if you stick out, you must be pulled down.
I was recently invited into a small discord group that discussed this very glitch in detail, and I won't say anything, at least not on this forum, because its aids, and it will get leaked.
