I'm Level 50 and Frost Hydra is one of my best skills. It does a lot of damage and it slows. Really nice.
I've found slowing to be really good at later difficulties, when it starts to get harder!
Also, on some of the harder bosses you might use different skills than for regular mobs.. (hydra is good on bosses)
Though that might change a bit when we get the nephalem buff..
And the fact that you can fire and forget a hydra for low cost, while you use your regular skills, make it quite a nice DPS increase.
Put it inside rooms and run out if stuff is hard:)
Same for blizzard actually which I think is a really awesome skill.

While you run around trying to avoid crap, it will do some dps for you.
