Random Silly Ability Idea

The Champion covers an area in ice. This area is a straight rectangular shape and widens with rank. Any Champion that travels on the ice is unable to move manually or with movement-affecting abilities with their Champion until they exit the ice or collide against terrain or Champions enemies to them, and they travel in a straight line in the direction and speed they were traveling in when they entered the ice. Ally Champions entering the ice gain a burst of Movement Speed entering the ice, as well as for a few seconds exiting the ice; this can only happen for each Champion every few seconds after the exit the area. Dashes which end inside the area cause the Champion to continue in the direction and speed they were traveling. Colliding with a Champion on the team opposite to theirs causes both/all colliding Champions to be stunned for 0.75 seconds, after which they are unaffected by the area until they exit it or the area disappears. Champions standing still when the area is applied over their location are not affected and any channels/recalls are uninterrupted.

Not even sure where I wanted to go with this, but it was a random idea I thought of. And I tried to make it powerful enough that even Yasuo would have trouble against it -- imagine, the OP Samurai that gets Pentakills upon Pentakills gets absolutely demolished by sliding on a sheet of ice and sliding into the enemy tower. Absolutely beautiful. I did make it at least slightly balanced in the fact that it affects ally Champions as well, except those standing still (so you can't troll someone trying to recall). Also, if you manage to have two champions (one of yours and one of theirs) collide with each other, BOTH are stunned instead of just the opponent. I'd say the champion that has this should be able to exploit stuns and lack of control, perhaps having their kit revolve around using the ice area. Hope someone can use this for any ideas they have :)
