Feedback:User/Thalanor Thornhale/Sylvary Skill: Pulling Vines

Motivation
I noticed that the majority of skills employed by a potent enemy that are of the area of effect type are of circular shape. Circular shapes but other shapes as well provide a strong disincentive to cluster. In another feedback post, I wrote about the general need incentives and disincentives to cluster up. Incentives could be providing benefits to clustering up such as the skills the Guardian has provide. This is a voluntary measure friendly players want to adopt at tactical moments.

To be clear, neither foes outside the largest circle, nor foes who are inside the inside circle are not affected - only foes between the circles. Foes who are caught are dragged back X distance towards the center of

Variation 1
The ring-shape expands around the caster of this spell.

Variation 2
The ring-shaped structure can be cast within a defined short range of the caster.
