The Target Type 2 Cone (For Tab Targeting) - Mystery Solved

[Audson]

Its still bad, because the target in the cone is selected randomly and not by distance.
When you have multiple targets inside the cone it often gives you an enemy far in the back you can't even reach instead of somethign right infront of you.

I was actually going to reply in a different topic about how tab targeting cycles, but since you mentioned selecting is not by distance. You are correct.
It does not function like the game describes.

Tab or Shift+Tab will always select the nearest target first. However, the next press of Tab or Shift+Tab WILL NOT cycle nearest to farthest or farthest to nearest.
Tab moves the Target Marker to the next target on the right.
Shift+Tab moves the Target Marker to the next target on the left.

Note:
I have Type 1: Ignore Depth set (so the cone on the mini map is ignored)
