The Long Way Around (achievement)
Try being a speargun/thief. Speargun5 is a teleport. I did that achievement with no problem.
I just finished. There was a way to approach those “mine fish” from the left and sneak past them.
Geez, this was almost as bad to figure out as the Ember Bay JP. Almost.
I know you are not entirely being serious, but: at least one developer at ANet does like challenges that are extremely difficult, and very few people can complete. This is, in fact, entirely legitimate if stored in the “few AP only” bucket where it makes no significant difference that people can’t get that achievement done.
