Guild Wars 2

To prevent any movement/shadowstep abilities. Theres no point in having cripple and chill that basically do the same stuff

But they don’t do the same stuff. Cripple is a simple movement reduction available to almost every class, doesn’t do much, can be done with everything.

Chill is less available and not only reduces movement but your recharge can take a pretty heavy hit, making you less able to fend of enemies.

Your argument is like saying: Remove bleeding please, it does the same as poison anyway.
