Feared mobs zig-zag like crazy after last patch
 

In addition to the known issue of Feared mobs running away too fast, they also now change direction every few steps, instead of only occasionally.

In classic, and up until the last patch here, their direction *might* change on each tick (6 secs). Giving a max of 2 direction changes per Fear.

Now they regularly change direction every 1-2 seconds.

This, combined with the extreme Fear run-speed, makes Fear kiting extremely hard (I suppose impossible for those without snare and sow).

Not necessarily what you are talking about, but I've made changes such that NPCs will rotate towards their next direction instead of instantly changing direction, pending update.
