Guild Wars 2

What’s the secret to managing to get this Vista?

I can get there easy enough, I’ve been there 6 times, and every time died within 3 seconds due to taking 11k+ per tick DOT off the green gas, yet I’ve seen three people run up and get it and two people were stood by me for over a minute trying to revive me.

Why do I die and they don’t?

Probably because they have the Itzel Poison Lore mastery.
