No it's not what I'm thinking of, you shouldn't correct me if you don't know what I'm talking about. The time spent close to the enemy when using jump as a poking tool DOES physically move your character and DOES put you in range of tank's vacuums if they're fast enough to grab you. You are also physically in range of casters and ranged DPS when you do this, because your physical position changes, and while it's true you return, it's often an INCREDIBLY bad idea because you have no control over your character, the longer the jump, the more time spent powerless.
