Guild Wars 2

I have a problem with vista in Human’s Lament. There’s no space behind the column, though in guides on youtube, there IS space behind it. I’m confused.
I attached screenshots, two of them are mine, and others are from guide.

Maybe some of you know what should I do in this situation?

Perhaps the video guide you were following was from an earlier version of the game, or perhaps from during beta. It does appear that the rubble wall has been moved forward in the current version of the game. Perhaps that was not the correct way of getting to the vista and it has been adjusted to block it off to encourage the use of the proper method of attaining the vista.

I’ll see if I can look into it a bit more to see another way of getting to the vista.

Oh! That vista!
Yeah. You have to go through the cave with cave trolls in it down to the right from the vista. This cave leads you right to the vista, though it is guarded by a veteran cave troll. There should also be a rich vain to mine in there as well.

I couldn’t help myself, I had to go check. It’s been so long since any of my characters had completed that vista.
Yeah, they definitely altered that to push you through the tunnel instead. No more hopping up that way.

Thank you, guys!
