Alot of people who main one class don't like the other classes jumps because they done know how to fully utilize them. I see the use in all of them.
DOUBLE JUMP is a quick jump that can be used quickly and can be modified to be one of the highest jumps.
TRIPLE JUMP is better than double jump because you can jump 3 different ways before landing.
BLINK is a fast instant jumy from one place to another. It can be used to foil enemys much like triple jumping.
GLIDE is a jump that is similar to flying. This can be used to quickly survey all of the surrounding area and there's even a perk that allows you to shoot while being sustained in the air.
LIFT is much like glide but it ore of a jet pack boost and is much faster because of it.

Lift kinda sucks not as bad as glide but still lacks the upward boost, double/triple jumps got the boost factor no matter how high you're falling. Blink is purely for combat, it doesn't go as high as any jump but it's pretty fast for evading/closing the distance
