How important is Sneak for a Druid? Halfling? Wood Elf?

[Vanessa]

When it comes to Druids, it seems like Wood Elf or Halfing are usually considered the best because they can use their "Hide" skill to break their charmed pets.

Stat wise Halfling seems to come out a bit ahead with 5-10 in a couple of the physical stats, and the 5% extra exp also. But it seems like the main difference between the two races is that Halflings get Sneak, and Wood Elves don't.

So I was wondering, just how important or useful is Sneak on a Druid? Would some of you Druids consider it a must have skill? Do some of you Halflings not even bother with using it?
