I am 100% for this. I do however think that adding invuln frames to Jump, while being awesome, would probably end up being pretty overpowered. The ability to change locations for the landing would make a ton of sense. The ability that definitely needs the invuln frames is Elusive Jump. The skill, as it is right now, is almost completely worthless. It CAN save your ass sometimes, but more often than not if you are really needing to use it, it's already too late. The fact that it doesn't record your location change until the time you land is just plain awful. With a long 3 minute cooldown, I think that it should be something we could use in tight spot to great affect. Spineshatter dive is completely fine as it is IMO. Also, I think the damage buff for the jump abilities needs a shorter cooldown. I know it would increase our damage output, but frankly melee dps classes (because of having to deal with positioning) should be doing more damage than ranged class... cough bards OP... cough...
