Guild Wars 2

Looks like that’s the vale supply camp. That’s where their spawn leads to. They’re invulnerable up there.

They are in their safezone. Their spawn is just a few steps back. Don’t get too close next time. Plain and simple…

Just to add some clarification, the next time you spawn from your border waypoint or from the citadel, check the buffs you have on your character. You should notice that you have the same invulnerability buff. This buff is only placed on a character when they are within their spawn zone. The moment they step outside their safe zone, the buff gets removed.

From the picture, it appears that they are inside of their safe zone and everything is working as intended.
