Personally, I'm using it when I have to wait for the global cooldown (as some of you mentioned earlier) which is good in itself; but I think that an even more strategical way would be to use it on another enemy one of your party members are targeting. It's not enough damage to raise that much of threat, so you won't pull the enemy towards you and won't end up tragically dying, but it's STILL some damage. We are DPSs (or whatever the plural is), and our job is to deal damage. So what do we do when we have to wait for our damage-dealing skills to cooldown? Yes, you guessed it. Do MOAR damage. If in the process you also help a not-so-nearby party member, you can even say "You are fucking welcome" at the end of it. Then when you'll have the Surge ability to boost the damage...just think: Blood for blood + Power surge + Life surge + Jump. Deadly.
