Guild Wars 2

Is that possible to disable this awful visual rectange around ground animation?
I understand that it may be useful for “pro” gamers, but i just wanna chill and enjoy my animations, i dont wanna see extra UI elements that destroy all atmosphere.

Thats the boundary of a fire field. I dont know if there is actualy an option to turn it off.

under options→ combat/movement → Disable Area of Effect Rings
