Is Bind Wound worth learning for a Shadowknight?

[Loadsamoney]

So that was a funny experience. I'm almost out of level 40 at this point, less than a yellow to go, and I start letting the mob I'm camping wear me down a bit more so I can practice Bind Wound afterwords. He gets me down to 20% which is where I turn on auto-attack again to finish the guy off, he's at 2% health, he gets a bash stun followed by a 160 Double (two 80's), I miss, try to root him, another Double for 160 and I'm dead.

So that's about two hours of experience to make up, all because I played very stupidly.
