I posted this in patch thread but it got buried under economy talk...
Lats night after patch, the attack proximity still is a bit whacky and has trouble engaging. One of our clan chased down a party and was under 100 metres for 15-20 mins (anywhere between 20-60 metres distance) before it finally clicked. He was quickmarching and moving faster than the enemy party the whole time.
either its buggy and still has trouble activating or the radius should be increase to like 100 or 150.
