Guild Wars 2

Hi, this achievement seems impossible without a set up. Is there any guild willing to set one up , as I really want this achievement done..
thank you

for those who don’t know:
Dispelling Shadows: Close the portals opened by the shadow behemoth in less than 20 seconds

Oh man

This was super easy (i.e. pretty much guaranteed) when SB only spawned those three portals right near where everyone stacks. I didn’t even think about this since the changes to its phases.

I do not envy people that don’t already have this. I got it when they drastically reduced SB life temporarily (I think it was an accident? some sort of scaling issue). not only did the massive zerg kill the portals in under 4 seconds, but SB itself was killed in under 20 seconds. some world bosses used to be MUCH easier to kill.
then again… anyone remember fire elemental the first few months after release? those fire balls that hit you before the red circle appeared, hit for 3/4 of your health, had a 3 second stun after the knock back, and hit every 2 seconds? ah the good ol’ days!
