The “Target nearest enemy” function now picks up targets that are behind the character, sometimes at quite a distance. This stops it being fit for purpose as a targeting command since you need eyes in the back of your head to make sense of what it is doing. (Players don’t have eyes in the back of their heads btw).
The fault is mentioned in this post too https://forum-en.gw2archive.eu/forum/game/gw2/Target-Nearest-Enemy-even-worse-now/first#post4404908.
