It would make more sense to rammus not being able to see when his W is on than crippling himself
Seriously tho, Why the heck would you cripple him? Urgot when he W he might be slow but he is almost a stationary turret Blitz when he W he gets a huge movement speed boost but is slowed at the end,
When Rammus W, he curl himself and sits doing nothing, screaming hit me please.
