I don't tend to sneak in combat, you can get spells that make it a little worthless such as invisibility and teleportation. I would probably stick a few points into it if you are planning on being a thief though, something i highly recommend. (You can't beat buying a load of goods off a vendor and then pick pocketing your money back)
