Removing all would have no effect.. The running ranged would never be slowed down without stagger. It would remain exactly the same as far as the balance between melee and ranged.
Almost every ranged class has two skills that help them create distance (bees+root, blind+quake, splash+circle+fear, trap+scatter, chains+teleport).
Melee classes are given one skill to bridge the gap rarely two (stealth, hamstring, charge+chop, fetters, exhale+tendrils).
If the gap never shortens between a class designed to run and another designed to chase, and the chaser is always out numbered in the skills used to counter distance then the imbalance remains.
