a concept for a twin shield champ

I have this concept of a champion with 2 shields, one on each arm, running around being a bad-ass and wanted to put it down on paper. Unfortunately this is a digital age and i'm all out of paper, so I'm putting it here.

Placeholder name: Flint

Faction: Noxus or Demacia

He would be a Fighter/Support

Now for the meat and potatoes

Passive: Protect and Sever - Gains a passive shield 10% of his bonus Armor and MR every 5 seconds out of combat. When the shield breaks gains the bonus amount of AD equal to 5% of his bonus health for 10 seconds.

Q: Rush Hour - Put his shields together and charges forward displacing enemies along the path briefly (0.25 sec) and causing damage equal to 20% of his max health. He takes 50% reduced damage from all sources from the front while using this ability.

W: Take Down - Grabs an airborne enemy and slams them to the ground causing physical damage (+AD%) (+10% their missing health) and grounding them for .5/.75/1/1.25/1.5 sec. If used on an enemy that is not airborne they are held in place and suppressed for .5/.75/1/1.25/1.5 sec instead.

E: Blinding Light - Reflects and flashes light around him for 450 units blinding all enemies in range for .75/1/1.25/1.5/1.75 sec and causing 20/35/50/65/80 (+AP%) magical damage.

R: Up and Over - Plants himself next to a terrain for 5/10/15 seconds and allows allies to use him to bypass the terrain. If recast within the time limit he can jump over the terrain himself. Gains a shield for 50% of his bonus health while this ability is active.

Welp. There ya go. That is my concept. I didn't put any numbers for stats because this is just a concept not an actual made to be used champ (yet, if ever), so I will leave that for people better than me to do. As always Any feedback is always appreciated. Thanks and GL HF on the rift.

Edit: put a few extra defenses on his Q and his R.
