I hope I can help you with this. The jump shouldn't be much of a problem. My guild does it with two Vanguard tanks currently and in this video with a guardian and vanguard, so we don't have the luxury of force sprint either.
We also have the same problem with DPS being too fast in our fights that we do now, holding for a few seconds shouldn't be an issue, usually we'll have our classes that can heal to pop off a heal or two while we wait.
If you have any questions I'd love to help you.
