Guild Wars 2

Can you please fix the portals in the Shadow Behemoth fight. I’m trying to do the Dispelling Shadows achievement but every time I try to hit the portals using a melee weapon I must then waste precious seconds because for some mysterious reasons my blows are all missing the target even though I’m standing right next to it, and trying to walk around it hoping to find some hittable spot isn’t of much use.
And with my ranged weapons I simply cannot do enough damage to destroy the portals in under 20 seconds, so please fix the hit detection on these portals.

Ranged attacks also miss objects pretty often – projectiles like fireball get obstructed or miss when shooting at portals, burrows, blossoms etc.
