What would people think of a negative passive?

As in, a passive that is something that makes the champion worse? for example, if they want the juggernauts to be slow but hard hitting, why dont we make a champion with a passive where they cant gain movement speed, at all. no boots, no champ boosts, no ghost. but in return, they can hit like a truck. to balance this, we could give them a slow resistace like ultimate. I think it would make it clear what the weakness of a champion is, since it is build into their kit. Thoughts? Also some more examples of a negative weakness and what kind of kit would you put it on?
