Personally I have nothing against circles, cones or lines. The one thing that I do hate is when combos and abilities changes from one to the other like old SAM. If they could stick with one style for a job similarly to DRG I would like it more. But it seems that they just decided to remove cones and change them to circles.

Cones did have the big upside in that you often could stand at the edge of AoEs and still hit most of a pack.
