Guild Wars 2

I cant see any aoe field which are created by foes. I checked all options already in my menu but nothing helped. Is this a bug or did i overlooked something in the option menu ?

It’s probably the following option under Combat / Movement:
- Disable Area of Effect Rings — Hides the area of effect rings normally shown on the ground.

have it unticked for AoE rings to show, had the same problem before.
