I tried to do a little research reading through the comments on Alla, but these are from 2004. There is nothing there indicating they run extra fast(just the high aggro range which was already correct on this server). In this post he even indicates you can quad them without pulling to chessboard which I believe would be impossible for anyone on p1999 server now. Please fix this back to how it was in classic as between the AC nerf and this run speed it is nearly impossible to quad these now without dying on a regular basis.
