Why do casuals act as if it's the end of the world when suggesting?

^This. And Fandaniel telling you to "stick to the shadows" would give a lot of people the impression you can do just that, sneak around the mecha and get to the exit. A better nudge toward what you are supposed to do instead of just expecting people to figure it out on their own would be quite handy.

So you are doing an instancied mission with a limited area to explore, the paths is completely blocked by a bunch of machines that are so many it's actually impossible to be in the rear of all of them simultaneously.
You have a magiteck armor facing them and shining like every "quest related item" since the start of the game and your first reflexe is to try to pass through the impossible instead of checking the shining armor that could help you ?
Plus, the game can't give you a false direction, since the area you can explore is quite limited...
