I use jumps all the time. It's just about know what makes them effective. I use Spineshatter Dive to traverse the field quickly to move between targets since using it as a stun can mess things up. I use Dragonfire on Titan during the Heart Phase if people are smart enough to run towards Titan when they get Gaoled.

To effectively use Jumps, they need to line up with your cool downs. Just using them in the middle of your rotation is a waste of DPS. I like to do HT > ID > Disembowel > CT > Phlebotomize > HT > Inner Release> TT > Blood for Blood > VT > Life Surge > FT > Power Surge > Jump. VT usually does about 1200 and depending on my luck, Jump will either do 750 or 1000. If you use Jump outside of your cool downs, it's kind of a waste at only 300ish. With the recast, it usually comes back around the same time as the rest of my cool downs, so it's just part of my big damage rotation.

If you're doing a fight like Titan, you can't spam jumps willy nilly or you're a liability. The only time you can safely do a jump is during stomps or a Goal targeting.
