Hah! I was not pleased when HIPS was introduced. I had a level 20 (top level in those days) Ranger/Rogue with very high skill in hide and move silently. In those good old days if you were a sneaky type, you plotted a route past enemies, using as much cover as possible, and kept an eye on a way of retreat in case you were spotted. Then HIPS came along and all the fun of hiding was lost for me : hit, step back, HIPS, advance, hit, step back ..... no fun at all.
So any stealth merchant complaining he was unable to use HIPS successfully gets very little sympathy from me
