The Random Ability Ideas thread

So, I just had an idea for an ability pop into my head, but don't feel like writing up a champion concept, putting together an interesting, unique, balanced kit, and all that jazz.

So here's a discussion to post random ability ideas that anyone gets but doesn't want to/can't write up a champion concept.

Here's the aforementioned ability idea- something along the lines of a knight's charge (different from Hecarim's) Ability: Valiant Charge (or whatever.) Champion readies and sets on a charge in the targeted direction. Charge is a dash-esque movement (moving about 1000 units/10 teemos a second) that goes up to 2000 units in a straight line (No turning) or until it hits a wall or an enemy champion. Upon hitting an enemy champion, Champion carries them with him up to 200 units and deals damage. If this hits a wall, the targeted unit is stunned and takes 150% of the normal damage. If instead the charge ends due to hitting a wall, Champion leaps over the wall if it is less than 200 units wide (2 teemos), and can cast abilities or take other actions while leaping. If Champion doesn't collide with a wall or a champion, he is fatigued from stopping the momentum of the charge, moving 20% slower and dealing 10% less damage with attacks and abilities for 2 seconds (smite &c. unaffected.)

The charge can be interrupted with Stuns, Roots, or anything that counts as airborne; however a charge stopped with these CC's does not apply the fatigued reductions.

Damage numbers would probably be between 100-300 with something along the lines of a 40% bonus AD ratio (150-450 + 60% Bonus AD with a wall hit). Since the ability takes up to 2 seconds to use, I'd give it a cooldown of about 14 seconds, and maybe reduce it by half if it jumps a wall.

Does anyone else have ability ideas or comments on this one?
