It does not attack in bgs i have read loads of people talking about this and yet no answer. it just runs around on the mount not dismounting and following the enemy, i actually have seen a person doing the same thing following me in bg we was both trying to attack each other on mounts it was very funny lol
had this same problem on my lock last night, uninstalled the logs and settings and redownloaded the singular routines with no results. hoping for an answer soon myself.
